I've had this sprayer for several years and I've been very pleased with the quality. I've never had a leak and the sprayer is easy to pump and easy to fill. The only thing it does that I don't like is that the back pack straps are held on by clips that occasionally become unclipped as you put it on. It's a bit of the pain to re-clip the clips while putting on a full sprayer. Over all though, this is a great tool that will last many seasons. Mine is over 5 years old and going strong.
