Negative Positive
Title: Poor Design.
Review: Yes, I read all the instructions. I pushed in the little button to make the chemical flow. It worked great as I held it by the hose and by the bottle making sweeping gentle motions. The problem is that the bottle pressure fitting comes off. Once it comes off, it is over. Putting it back on, it remains loose and will either work for a 30 sec period of time, spray you in the face, or just pop off. Garbage product, Avoid.
