Gauge looks really cheap but the tool itself seems to work well and metal quick fitting. Was not zeroed when it arrived but I just had to relieve the pressure in the tool by depressing the schrader valve in the end and it went back to zero. Very happy with this tool

Works great compared to oem I've had to purchase 2 oem tools in past. Very comparable to the oem tool. Used on a daily basis helps with the diagnosis of duramax fuel system.

The gauge is very well constructed! the hose is long enough to tape the gauge to the windshield to diagnose drivability issues. Great buy!

So far, the tool works as it should. I saw some reviews about it getting stuck at a certain pressure. If yours does that, press the center part of the fitting that locks on to the truck test fitting. It will release the pressure/vacuum and it should zero out again.

The needle doesn't rest at zero, hard to tell when using what is happening.

Very good quality, worked very well to diagnose a customers truck. The price isn't bad. I briefly tried to find the quick connect adapter to use with my other gauges but I could not find any one selling just the adapter.
