Rated 1 out of 5 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 out of 5 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 out of 5 by Stay away from this product My diaphragm started to leak after a year of regular use. No spare parts and no warranty. $120 down the drain August 8, 2014
Rated 1 out of 5 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 1 out of 5 by Cheaply made Within a week, the plastic clips that hold the straps broke. I had to tie them in a knot at the bottom. Liquid seeps out of the wand and the pump area, spilling dye on my garage floor. When using the sprayer, the lid will leak and allow chemicals to run down your back. I am so dissatisfied with this sprayer. I would have gladly paid $30 more for a good quality product. I am so tired of junk and cheaply made products. This product is also generally delicate. You cannot just put in the back of a pickup without worrying about something snapping in half. The good? It sprays a nice pattern. The pressure builds with a short number of strokes and the pump has worked well for me other than the leaks mentioned. May 30, 2014
