Worked a few years just like magic until the brass connection broke in half but for a constant 3700psi running thru it and for $20 who cares. I bought another for another few years. This a must have if you pressure wash. Goes from zero to max and all in between as needed.
Pros: Easy to Use, Easy to Install, Looks Great, Good Size & Weight, Nice Design
Cons: cheap brass inside, tends to leak a little

Review 2 for Pressure and Flow Controller for Pressure Washers
Bought pressure washer flow adjuster and used it yesterday to adjust pressure up or down. It works just as it should. I like it very much for that purpose.If you feel you may harm something from too high a pressure you can adjust it down. I would recommend it.
