I am a relatively new pressure washer owner and the first inconvenience I encountered was having to walk 20 yards to shut off the water each time I needed to change attachments. This valve will eliminate the need to do this, adding a lot of convenience to my jobs! It's a tad heavy at just under a pound, but it definitely has the feel of quality materials and the valve itself engages securely without being too difficult to turn by hand. I highly recommend adding this valve to your pressure washer, if it doesn't have one already.
