So far I'm very happy with this hose *BUT* If your after the most GPM you can get out of your machine. This hose is not a true 3/8 hose it has a smaller inner diameter and as sutch it may not be the hose for you. My washer makes every ounce of 4400 PSI but has a lower GPM so this dosant really apply so much to me. Iv also used it on an electric 1900 psi machine to some relatively impressive results. Time will tell on the longevity of this hose. It's thick and durable iv stepped on it and kicked it (I don't reckomend doing that) But I am curiouse scientifically curiouse as to how long and how we'll this hose will holde up for me. So far it's doing what I need it to. The quick release is solid. It's honestly not the smoothest feeling quick realease iv ever felt. But it works with no issues so far. Yes there are better overall made hoses in the world YEAHH they also COST better made. And the reallity is a hose like this is far superior to anything your oing to be getting out of the box with the pressure washer you just bought. This hose is more than fine for the average home owner and those are the people thst are going to be buying this hose anyway for the most part[EDIT]IMPORTANT One fairly important point that compleatly slipped my mind. It's possible that the over all length of the quick connect attatatchment setup will imterfear in some narrower pressure washer set ups it all depends on ware your outlet is located in proportion to the handle bar if I wer using the handle cart my washer came on I would have had to physically cut the bar just bellow the port to atatch it. The problem in my case is the stem inside the hose protruds an inch maybe even an in and a half down the hose thus not allowing it to flex. The combined over all length would be a no go ells wise. And it's actually the pump manufacturer (why would you build somthing that way?) thats the problem. So BEFORE you pull the trigger on this be sure your outlet isn't directly lined up with your handle bars like mine was. Or be prepared to take mesures.
