Beyond what I thought it could do
Style: Corded Lawn Mower
It's 10:32pm and I just got finished cutting my entire front lawn and 2/3 of the rear. Only stopped because of time and lack of light. So happy, I'm writing this review this late. My jerk of a lawn guy decided to stop cutting my grass without notice because I wrote him a note about cutting my grass too low. Seriously, indoor carpet is longer than what he does to my lawn, which burns it, hence the grass looking the worst it's ever been in 20 years despite a good rainy season. Sorry, getting off track. My lawn quickly became overgrown (with me waiting for the lawn man like an idiot) and without fail, the city was quick to post a violation. This weedwacker came in 1 day. I figured it would last for at least the front yard. It did more than that, and will be ready for tomorrow too. I honestly thought it would bog down in high grass like both of my old gas mowers used to do, back when I cut the grass. Imagine my surprise when it didn't. It just kept cutting away. Is this thing going to replace your mower for medium to large yard, I would be lying if I said yes. Will it cut your grass faster than a real mower, again no. However, if you have a small patch of grass to cut, or have an emergency like me, with the city breathing down your neck, get it. It is super light weight and even though it took me longer than a regular mower, I had zero fatigue, aches, or pains. Even if this thing doesn't last, which I don't have any reason to think that it won't, it was less hassle to buy and use than going to the box store and renting, cleaning, then returning a lawn mower. Even if it were to break down on the 2nd or 3rd use, it's more than paid for itself as far as price and ease of use go. Seriously, this thing has preformed beyond my expectations. I know it's performed beyond its intended design use in my case. If it does happen to die soon, I'll update, but honestly, the electric motor didn't seem to strain at all. One last honorable mention, with the lawn attachment on, it was fairly quiet (which is why I kept working so late). I hope this review will help anyone that finds themselves in a similar situation. The bonus for me is that I can give my former lawn guy the finger the next time he cuts my neighbor's lawn across the street because now I have time to find someone that won't actually destroy my lawn when they cut it. ... show more

Easy to put together, does the job, excellent trimmer and edger
Style: Corded Lawn Mower
I don't have a huge yard so was looking for something to get the job done and can easily avoid sprinkler systems and drain pipes. 10/10 recommend. It was like vaccumming with a light vacuum. The trimmer and edger was so easy to use. I am not that strong and the trimmer was light weight and easy to maneuver. The guide for the edger was just what I needed because I was worried about cutting the line on the sidewalk. I got around garden rocks and everything. ... show more

“Bubble mower”
Style: Corded Lawn Mower
I called this my “bubble mower”and do enjoy using it. It is easy to transform it from a mower to an edger to a weed whacker. With Black & Decker quality and performance a gas free alternative. I enjoy using this mower however with my large front yard it does take a little more time than a conventional mower. Truth be told secretly I wish it did blow bubbles as well. lol. ... show more

Lowest Mower Height Answer: 22 1/2 inches!! :)
Style: Corded Lawn Mower
Review Image by Just Me
Review Image by Just Me
Like others, I needed to know the lowest measurement setting from the ground to the operating button with the mower attachment and trimmer in place. For some unknown reason, the community answers seemed to avoid such an easy question for those who owned one?! With that said, I just purchased my own to get that exact answer with a measuring tape. The LOWEST MOWER HEIGHT (from ground to button pressed): 22-1/2 inches. The HIGHEST MOWER HEIGHT (from ground to button pressed): 31-1/2 inches. **Due to my very own physical needs, the lowest height works perfectly for me! Fortunately, I did not have any of the 'troubles' that some have reported with theirs. If it works as it all did with my first use on a small yard today for even a season or two, I would definitely purchase again! Although it does kind of sound like a small shop vac in use, it is absolutely adorable and FUN for me to use. I love it!! It does look like a toy and is nearly identical to vacuuming (with both physical motions & width). So those that are impatient, hate vacuuming or want to look 'manly', may not appreciate this trimmer/mower like I already do. Did I mention that I I love this thing! :) However, as not to wear down the thin and very narrow plastic lip that holds the trimmer into the mower attachment, I personally won't be pressing the trimmer into the mower attachment until it "clicks" per the instructions. Instead, I simply press on the pedal and gently seat the trimmer all the way in before releasing the pedal to lock it in place. Noting again, that's just my own suggested solution to hopefully prevent that thin plastic 'lock' from wearing down so easily, or as I see that it probably could otherwise. Further, the trimmer seems to hold in place just fine when pressing the trimmer handle down to make turns (just like placing the weight on the back wheels to turn a vacuum). To 'lift up' on the trimmer handle when mowing, is when it wants to detach from the mower --so don't do that people lol. Just like every electric tool that I've ever owned, it does NOT come with an extension cord (and it makes me laugh that anyone would expect it to). However, since I wanted an extension cord designated just for this unit, I also purchased what did NOT work --and that was a 50 ft 16AWG Yellow HUANCHAIN brand through Amazon at the same time as well. To my disappointment and even trying to force it further into the plug hole, that extension cord does NOT and will NOT make a tight enough contact to fit but for 'brief' contact spurts. At first, that was a big GRRR there for me because the mower kept cutting out before I realized it was that extension cord that was barely making contact. Okaaay.... **Instead though and most fortunate for me, I ended up using my older orange extension cord (that most of us have laying around) that has a slightly narrower plug encasement ... which seats all the way into the plug for continuous contact well and fits perfectly tight! With my recent experience: If it feels slightly wobbly, kind of loose or pulls out too easily... just forget it and try another extension cord plug! You're welcome. Lol Again, before getting super frustrated with the extension cord constantly coming loose from the plug (like I did with the brand new yellow one), you may want to try to find an older style or better fitting extension cord first (even if to take the trimmer to your local hardware store to try one there)! See my extension cord pics as example: Orange (narrower) = Perfect & Tight Fit! Yellow (chubbier) = Frustrating, Loose & Horrible Fit!! Lastly, my reason for purchase: Living in an apartment with a small yard has became just too ridiculous annoying every year to 'wait' for yard maintenance not even mowing until the weeds are almost 18" high and allowing the clippings to just fall where they may for their tenants to just track long grass/weed clippings into our cars and apartments -- I finally had ENOUGH when a thorn weed recently caught my pant leg causing me to trip and fall! With this fun to use, light and nifty little edger/mower that I can enjoy taking care of my yard weekly and all by myself... I won't and NEVER will want such careless "yard maintenance" in or around my yard (or vehicle) again now anyway! I'm not done yet but just after mowing the whole yard once & quickly edging to 'test' it today, my yard already looks way better than it ever has before! I'm HAPPY and very pleased with this fun little B&D trimmer/mower being my new 'toy'! The only reason I'm not including pics of the results with its use on my yard today is due to some privacy concerns but it already looks GREAT! Yet, I hope my lengthy review helps answer some of the questions that I had prior to my having to purchase it to find out for myself anyway. I'm sure glad I did though! I don't enjoy raking so to prevent that, I will just be sure to mow weekly through the growing season because I CAN and will enjoy doing so, too. Just make sure you get a tight fitting extension cord and well then . . . Happy mowing the easy way!! :) ... show more

Awesome workhorse
Style: Corded Lawn Mower
I should have taken before and after photos. However this thingwork like a charm, becaues I was abit overgrown I was hoping to at least trim it down until I could get a regular size lawnmower, No need, this thing cut down 2 foot overgrowth like a beast. Theere is a bit of a learning curve, you need to use a sweeping or back and forth motion like vacuming, this is basicaly a weed whacker with a deck attachment. Which brings up thone of the only 3 downsides I have: 1- the clip holding the unit into the base needs to be stronger, 10 minutes of use and it started to come undone when I picked it up, frequently cleaning of grass build up helped somewhat but in reality the clip barely touches the lip of the unit, snapped in perfectly when first started. now it comes undoe very easily. 2- the height setting are useless , I need to keep it at the highest setting otherwise the spool drags the ground and the wheels don't all reach the ground evenly. I placed it on the cement walk way just to make sure it was not the ground being uneven. nope, the spool hangs down too far. 3- and lastly, the trigger should have a lock to hold it down, like a small toggle or deadmans button under the palm part. It is nice that you don't have to grip it too hard to keeping it running but it does getting a bit fatigueing. Overall though, I recoomend this Item. It does what it says and a little more, not for heavy duty yard work or a large lawn but for small to maybe med sized ares it is perfect. I also recomend either buyng more spools or replacement line. along with it. but that was just poor planning on my part, as I stated earlier, I was a bit overgrown. 3 out of 5 for the 3 reasons liste but 5 stars for everything else. ... show more

Absolutely worth it
Style: Corded Lawn Mower
I have a small backbyard that I am responsible for maintaining, but I didn't want or need a large mower. This combo is convenient and works exactly as expected. The motor is not quiet, but it's not so loud that it would impact anyone inside. The handle is adjustable so I was able to mow easily without bending over, and when it was time to store, I just had to twist it down. The mower is powered by a cord so you will need a heavy duty extention cord since it does not come with a cord. But since it is corded, You don't have to worry about running out of battery life, so win win. Just make sure the cord is long enough. Overall, this is a great replacement option from the edger I was using previously. This is easier and I get 2 in 1. Very much happy and would recommend. ... show more

Don’t buy it!!!
Style: Corded Lawn Mower
This product is not worth buying!!! I bought it because of its interesting design and its price and the brand name and because I have a small yard and our lawn guy pissed us off because he wanted to charge us $35 every 2 weeks whether our yard needed to be cut or not. This design was a great idea but needs to be done better. The first and biggest problem is that the 2 pieces come apart too easily while in use. The second issue is that the line only lasts for about 1.5 cuts front and back. Our lot size is about 7000 sqft including a 1700 sqft home on the lot. I believe the backyard which is the biggest of the 2 yards is about 45x35 feet and the front is about half this size. The trimmer grab handle needs to be able to rotate for edging. The replacement spools are expensive and getting harder to find. Walmart is now selling their own line of Lawn Care equipment and no longer sells B&D replacement spools. I purchased the less expensive system that uses an extension cord and it is very easy to run over the cord which will damage the cord casing. I made the decision not to buy the rechargeable system because the reviews stated that the batteries only lasted about 20 minutes each with an added cost of around $70 almost double what I paid. My lawn takes me about 3 hours to cut with about 2 15 minute breaks included in that time frame with this machine. The deck has no adjustment for height and so the grass is cut too short which causes it to burn easily in the hotter months. There is no grass catcher so it leaves clumps of clippings all over the yard depending on how high the grass is when you cut it. The trimmer being used as a blade is not very effective for cutting grass so you have to go over the same spot several times to get an even cut so that your lawn looks uniform. Also the width of the deck is considerably smaller and doesn’t cover as much ground. The trimmer loses its effectiveness as the line shortens so you will have to constantly stop and release more line several times to finish the task of cutting your lawn. If you have to have something cheap in a pinch it does work and at $89 I have already paid for the machine with the savings from cutting my own lawn and there is a lot of satisfaction afterwards when you know that you have cut your own lawn to your own level of quality. So unless you are very patient and have some extra time be prepared for at least 3-4 hours in triple digit heat and many moments of frustration especially if you’re located in Texas like I am. I’m in the Dallas area so it’s probably going to be even hotter the closer you get to Houston. I will probably be replacing this machine with a more expensive larger rechargeable mower with a bagging attachment and a much better quality rechargeable trimmer. A blower is also a must because you are usually too tired to sweep 🧹 and it takes forever too. You get what you pay for but I have paid for the machine with the savings from 3 cuts at $35 for the service. ... show more

BEST Little Mini-Mower
Style: Corded Lawn Mower
I needed something for our flower beds cuz I'm old and it hurts my back to bend over and snip. Not fond of weedwackers and was doubtful purchasing but let me say, this 'mini-mower' is sooooo perfect for our needs. So happy we made the decision to buy it. The weeds do not go flying out and about and covering yourself like typical weed-wackers do. But because it's a mower, the grass stays below inside under the mower part. And lightweight, I can pick it up and place it in the flower beds. LOVE it !! My only regret is I didn't look years ago to see what was out there to help us with our lawn/yard trimming/mowing needs. Neighbors will probably laugh at me thinking it's a kid-size toy. lol...But wait til they see the results! Thank you Amazon for making our lives easier! UPDATE ON USE - I did find when using the lawn mower, the little tab that holds the weedwacker spool slips off and the weedwacker with handle comes apart from the base. What my handy husband did was use a zip-tie thru the black hoop underneath the handle part and around the handle securely so when I lift it to place into my garden it doesn't come detached. I LOVE this mini-mower. To mow with it, it is fine but if you have to lift it over something, be careful; the orange tab is not long enuf to secure it to the base. But this one flaw didn't deter me from owning it but wanted to share my experience. ... show more
