Rated 1.0 out of 5.0 by Not even comfortable giving ONE star! Out of the box it felt cheap made for the price. Worked fairly well the first time around the yard. Second time after I mowed I drug out the sprayer to put down some roundup. Never got through the second use before the pump part, diaphram whatever, broke. Cheap plastic parts where it takes the most abuse such as the pump. No wonder a large part of the instructions is about how to order repair kits for the pump. Now I have to decide whether to take this back to Home Depot or write it up as a lesson learned and see what brands are available at other stores. Been a BIG fan of Home Depot for years but the more I see cheap junk in the stores, the more disappointed I have become. April 6, 2012
Rated 2.0 out of 5.0 by Hoped For Better Quality I have had this pump sprayer for just less than a year. For the most part it work well however it’s the products durably I feel is this lacking. The hardware came apart and needs thread locking compound to keep it from falling apart. My biggest complaint is the tank. I use it in a professional landscaping business so it’s out in the sun every day and the tank has become bridle and developed a large crack running along the top of the tank and finally where the shoulder straps connect to the tank is woefully deficient. I don’t understand how a designer could use so little material to keep the strap in place with a tank that could when full weight 30 plus pounds. I have replaced the tank for $22.00 but I am looking for a replacement for the sprayer. October 3, 2010
Rated 1.0 out of 5.0 by Do not buy this product. I use backpack sprayers about every other day at work, and Ive noticed that over the last several years they are progressively lasting a shorter period of time( all solo sprayers). I bought this one and it hasn't even lasted six months. The main problem is that the gasket around the lid never totally prevents leakage, even when new. After a month of use the chemical will just pour down your back when you walk. Also, my spray wand has failed at three places. The valve doesn't work right. The wand leaks when it is hot outside. And the wand also leaks at the point where the tip connects. Do not buy a solo product!!! Save your money and get an SP or Birchmieir. P.S. you can't find replacement solo parts when they fail. If you're able to, the cost is a significant percentage of buying a new backpack altogether. I'm surprised Home Depot carries such a low quality product. July 11, 2012
Rated 5.0 out of 5.0 by I think it is awesome I'm a "lazy can't stand to do yard work" kind of guy and I just moved into a place with a huge yard... all over grown with weeds. I hired some laborers to weed it and it was looking pretty down to the dirt (in May) and then it rained like crazy again so up they came. Went and bought this guy and got the whole yard done on one 4 gallon batch of round up. I'm a happy camper. Yes the chest strap is a little funky but not enough to take a star away in my opinion... the shoulder straps work great and holds it in place well and the chest strap is fixed with a knot on one side. It went together VERY quick with a 13mm socket and wrench (I think a 1/2" will work as well as a pair of pliers if that is all you have) and that was it. This thing is cool... the fill opening is very large so filling and mixing is easy, it has marks on the tank so you know how much you are adding. One small warning... 4 gallons weighs a few pounds... filling it on a table where you can back up to it and "step into it" rather than picking it up and trying to swing it on like a back pack will save you a lot of work. Make sure to tighten the shoulder straps so it sits high enough that the "stand" (a bar that is bent into a C shape) doesn't hit your back when hoisting it around. It is simple and effective... you cruise the yard, pump with your left and spray with your right... or switch it the other way if you want in probably about three minutes. I thought I would want it the other way, not sure why and I am right handed but the way it comes set up for right spray works best for me. I have a very bad back and this addressed an otherwise sometimes backbreaking job... it made it easy and manageable with NO strain on the bad back. It doesn't take much pumping to get a VERY strong stream or mist/flow and it pretty much stays that way through the tank, a few pumps goes a long ways... and the pumping is so easy that it really doesn't feel like much work at all. The brass spray tip adjusted VERY easily giving me a quick dial in to the right spray AND it did not change or require adjustment at all during use. All things considered... price, what you get, how well it works, how long you expect it to last... I think it is a bargain and would by it again in a heartbeat if it came up missing. This thing is a winner... you will make short work of a dirty pain in the rear job in no time at all... and with a 4 gallon tank you will get the whole yard in one shot or have some left over for touch ups. This is one lazy guy that got back to his usual self in record time with this baby. 5 stars all the way. May 27, 2011
Rated 1.0 out of 5.0 by Backpack sprayer is great just not this one This is the second sprayer that I have purchased. The pump broke after several uses. I purchased repair parts but was unable to get it to work. I then purchased another one. I should have known better. After two uses it is now out of commission. I am going to attempt to return it but I have my doubts. A backpack sprayer is definitely the way to go, but this brand is not the one to get. June 3, 2012
Rated 4.0 out of 5.0 by Very good product Very easy to assemble and use. Used 1x and worked very well. Sprayed just the visible weeds on 1/3 acre in about 1/2 hour with little effort. Pumps easy, cleans easy. Suspect it will hold up and work well. Somewhat difficult to learn what spray nozzle does what - but that is probably more me than the product or directions. No good spot to secure unused nozzles- easy to lose them. July 10, 2011
Rated 4.0 out of 5.0 by Backpack sprayer RL Pro 4 gallon The unit seems strong and well built. The actual operation instructions were a little weak and the pump handle does not stay firmly in place when you are pumping with it. Perhaps betters instruction with clearer pictures would help?

Rated 3.0 out of 5.0 by Sprays well, but low quality parts Bought the sprayer this week to assist prepping a cedar fenceo for staining. Assembly was easy and straight forward. The big disappointment are the clips that hold the shoulder straps to the lower frame. Both have broken in 3 days of use. I will seek out new ones or just sew the straps to the frame. Just be prepared to lose some time dealing with this problem. Otherwise, i have enjoyed the convenience of the higher capacity and the srayer works well. April 6, 2012
