They also sell the
Kwazar Venus Super Compression Sprayer Pro.
I have used the AG one for a couple of years for rinseless pre spray and it works great. My only complaint is the small bottom makes it easy to tip over and I don't care for the trigger lock. I picked up a Kwazar a few months ago and really like it. The bottom is much bigger and haven't tipped it over once. It also dispenses a larger volume of product so less time spent spraying. It is expensive compared to the AG version.
