I had bought a 2 gallon Solo a couple of years ago. This 3 gallon sprayer I had recently purchased had more attention paid to the leaking gasket around the outer red cap where it screws onto the tank. It had more grease applied and seemed fairly leakproof when I used it last fall. As you can see in the photos there is a handy container for extra sprayer ends. The hand pump works well. However, I don't use the shoulder strap because I have to set the sprayer on the ground to repressurize the tank, plus carrying it by handle puts the spray nozzle closer to the ground. I had noticed a reviewer said he needed directions for attaching the strap so I included a photo of how to do it.An added benefit that I wish the manufacture would consider is a quick attach/release of the hose and wand so that the outer red cap can be easily unscrewed when cleaning the tank. A better solution would have been to shorten the red cap inside the tank so that the contents would drain completely without removing the cap. Also, I found the wand holder was too loose letting the wand fall out too easy. I put some electrical tape around the holder so that the wand had a tighter fit when it was mounted to the tank for storing, etc.I do like the translucent tank making it easy to check on the remaining liquid in the tank. Using the handle to carry the tank in one hand and with the wand in the other hand makes this an efficient sprayer to use.Of the various sprayers I have used, and after evaluating what is on the market I have found this Solo sprayer fits my needs the best.
