  • Nice sprayer
I just got this sprayer recently. I do pest control for a living. This is a great sprayer so far, have only used it a few hours so far. It has a very good vertical spray distance and the extendable metal wand is nice. As far as longevity and how it holds up to abuse is to seen still. I am keeping my fingers crossed it holds up because so far it is great! ... show more
