Style: Corded Lawn Mower
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!! :)

Easy to assemble, easy to operate on the 3 modes. I was particularly impressed about the easiness and quality of the edge trimming and for the creativity of converting a string trimmer into a string mower by simply snapping it into a mower support. It is very light and easy to handle. As a string mower, it can easily be handled with one hand and feels like you are vacuuming a carpet floor instead of mowing a lawn. As an edge trimmer, the small wheel assists in guiding the motion as well as keeping control of of the precision, requiring less efforts than a trimmer that does not have that assistant component. As a string trimmer is where I don't see this product much better than other options. It is very light and easy to handle, but so are others. To me, what makes this a great product is because it is really an effective 3-in-1 and very easy to maneuver on those 2 applications where a conventional string trimmer is not as good or as easy. I really like it.

I am giving this 5 stars even though I was incredibly disappointed. I did have high expectations, perhaps. This is a corded trimmer and if you do not need to go very far you will LOVE this. I absolutely did!! As a trimmer is was an excellent trimmer and a great experience! The mini lawn mower attachment - definitely not. That is why I am so disappointed. I was so hopeful.... It just was not up to the task at all. The videos make it look like it runs like a breeze. I did not have a large area to do either. The grass is thick though. That could have been an issue. I still love the trimmer and still use it close to the house. It does a really great job. Better than the big industrial one I have for the rest of my yard. I have a huge yard. If I could trust putting a lot of cords together to use this one for the other areas, I would. I think that would be extremely dangerous and I am happy I bought this even though the main feature was not what I had expected. Still a really good product.

Overall, I like this little device. It is light, compact, easy to use and to assemble. It cuts the grass well and creates a smooth finish. It has a few negatives to point out. The weedwacker part pops off easily during cutting if the plastic bottom gets full of loose grass or if I run over a bump or go down a steep hill; it also pops off with sharper turns. The first cord I tried did not fit the narrow plug that the lawnmower has. I had to get a different cord and use another extension cord to allow it to go a decent distance. The cords are a pain, they get stuck over rocks and debris and get unplugged, so have to take multiple breaks to fix that. The plastic bottom needs to be cleaned out frequently from the loose grass, otherwise the mower does not operate as it should and the top gets loose as I mentioned earlier. I wish this would have come with the option to also have a battery, not just either or. This would have allowed me to go to the father places in the yard where the cord does not reach, no matter how long it is. Still, I do like the convenience of the cord and not having to recharge the mower. Last thing to mention is the constant need to be squeezing the trigger on the handle to have the mower running. This makes my hand quite fatigued if mowing for prolonged times. I wish there was a button to keep the mover on without having to constantly squeeze the trigger.
