Works great and the included extensions are added

Works great to quickly “sweep” off the driveway and pool deck without leaving a lot of water behind and without applying too much pressure to the concrete surface. I also used it to clean under my trucks. The included extension are great and useful for other projects as well

Incredible quality for the price

I did not expect this to be made entirely (it appears) of stainless steel and brass. For the affordable price, the quality amazes me. I use it for washing the underside of my Landcruiser after overlanding trips where it's common for the underside to get caked with mud, and in the winter (horrors) road salt. For that it works great. I honestly can't see how this thing could be improved. I only wish I had bought it earlier.
