Bests & Worsts Reviews from Amazon

I received the unit and when I hooked it up to my pressure washer, it didn't work at all. All my other attachments worked fine. I tried it on my neighbor's pressure washer with the same results, so I returned it for a replacement. When the replacement unit got here, it worked for about 3 hours. The next day I hooked up again and it didn't work any longer (like the first one the pressure washer worked fine, but could get no flow through the attachment). I returned this one also, but requested a refund rather than a replacement.
