Hi,
I actually had this item, and it worked fairly well for about two uses, but if you accidentally plug it in with the switch on without water flowing, even for a few seconds, it blows the seals, and the pressure washer will no longer work. I did this, and a second after realizing it was on, I immediately unplugged it, and it never worked again. It was my fault, however I am not sue that it should have failed after a second or two. If I had a kink in my water hose, this would have also caused the failure. If you make sure it always has 100% water flow, then it may be just fine. The hose connector was also very difficult to connect, so make sure that yours turns freely if you get one. Hope this helps a bit!
