Excellent Backpack Sprayer
Size: Backpack Sprayer
If you need to apply weed killer to a large part of your lawn, get this sprayer. It's worth the money. I used to use the small 1 or 2 gallon sprayers but didn't realize how awful they were until I purchased this sprayer. The features I like most are the ability to pump up the pressure while I'm spraying. This alone saves a huge amount of time when spraying a large area. The size of this sprayer also makes the job easier. Mixing 4 gallons of herbicide once beats having to stop over and over again to mix another batch like you do with a small sprayer. This sprayer comes with several spray nozzles. I especially like the fan nozzle, as it allows me to spray a large area in a short amount of time. Carrying this 4-gallon sprayer on my back using the padded straps is easier than carrying around a 1 or 2 gallon sprayer with a single shoulder strap. Compared to the smaller sprayer, this sprayer feels heavier duty. I look forward to using it for years to come.

More than 1/4 acre? GET IT!
Size: Backpack Sprayer
Okay, so I've never used a backpack sprayer before, so this isn't a review comparing this sprayer to other backpack sprayers, it's for all of you that have used the standard pump up sprayers and are just tired of it! I'll make review simple, if you have more than 1/4 acre or so of land you want to spray, this will probably help you cover your property 4X faster or more! Here's why: (1) It almost completely eliminates foaming, WAY better than a pump up sprayer. I think I waited a few seconds for the foam to go down. (2) It holds double the product of a standard 2 gal pump up sprayer, which is obviously better (3) You can continually pump up the sprayer while spraying, without ever stopping. AND, it takes about 1/5 the amount of pumps to get the same strength of spray (4) It comes with multiple spray tips that offers some really precise spraying (I like the black adjustable tip personally) and some wide fast coverage (5) It covers a LOT of area fast. (6) It has an angled head so you can stand up straight and spray without killing your back (a huge plus for someone tall like me) (7) It has a couple of filters to prevent the dreaded clogged nozzle, I never had a single clog after 12 gallons of product (8) It's really reasonably priced for the quality and time savings. The ONLY thing I didn't love is that it's kind of hard to see how much product you have left without swinging it off your back to check. Not a big deal, but just one little thing. Other than that it's great, a huge time saver.

Good but not perfect
Size: Backpack Sprayer
This sprayer works great and was easy to set up. Good pressure and nice size tank to get a lot of area done. The backpack straps are very comfortable and easy to adjust. The only real issue is that the tank does leak when full and my shirt was soaked by the time I got done. Wasn’t a huge deal for what I was doing but would be if it were a hazardous chemical. Just be careful with how much you fill it and what chemicals you’re using.

I have three different backpack sprayers this one's the best
Size: Backpack Sprayer
This one costs about $15 than one of the other backpack sprayers I bought, but it works so much better it's worth the extra cash. The pump is easy to use and it's mechanized inside so that one pump is like 15 pumps on my other backpack sprayer. All of the seals are tight and the backpack straps are very comfortable. Other sprayers the straps are too wide and they fall off your shoulders when pumping especially when the tank is empty. This one has a little bit more narrower straps. Maybe if your built like Paul Bunyan the other kind is better but for a normal size guy like me this one's the best. The wand is made out of plastic but so are the other two on my other backpack sprayers. It comes with different nozzles which my other sprayers didn't a flat spray or a round spray. All the seals are really tight compared to other sprayers some tend to lose pressure when not pumping over time I set this one on the shelf overnight and it still had pressure in the morning.

Killing weeds has never been more fun!!
Size: Backpack Sprayer
I just sprayed an area about three times the size of what’s in the photo today. It was purely amazing. This sprayer made light work of it. It took me a little under 3 hours to spray all of it. Originally all I had was a hand held one gallon sprayer from Lowe’s that would have taken at least half a life time to spray what needed done. I ended up using every chemical I had left in the garage, hoping they were still good. If not - because of this machine, and only because of it, I will spray again. ((Fortunately I did not have to!)) Easy to put together Multiple sprays tips allow for an array of spraying I’m 6’2” with a belly & it fit wonderful Very ergonomic and easy to put on and carry around completely full. Great design with some thought into it. Spray lock is wonderful. Year 2 - pulled it out mid summer to do some spraying and the machine worked like it did the first time I used it. No problems at all. Stored her outside in the garage. Not heated or anything. I cleaned her really good with just water and that was it. Very happy with it. I’ve used it a total of ten times, but every time was a good few hours of spraying everything for everyone.

A common sense review.
Size: Backpack Sprayer
This is a great little sprayer. First, for those that complain about the weight use your head and just fill 2 gallons at once instead of 4. Second, for those complaining about the seals. It's not a hot air balloon, so don't try and pump it up so much you float away. Third, to the ones complaining about the shoulder straps, a small piece of Velcro loop or in my case a 6" piece of 12/3 makes a perfect little cinch for across the chest. A little common sense goes a long way.

Fails to hold and accumulate pressure
Size: Backpack Sprayer
Assembled and put product to use one time. Product performed great and sprayed with great pressure. 1/2 way through the spray job the product would only drip solution out no matter how many times it is pumped. Took pack off and placed flat on ground and pumped more, gained some pressure and would spray upright for a few seconds before quickly losing pressure again. I am guessing the seals are busted after 30 mins of use. Don't buy this product its not built to last. Was hoping to at least get a few years out of it, but less than 1 session is clearly unacceptable.
