Received it and immediately tried to use it. With all the great reviews it had, I was thrilled to get it as it's something I've been without for far too long. Unfortunately the plastic they used to cover the outside of the intake screwed up the 1st thread line. I can't screw in the included quick-release chuck without bending and twisting the threads. I'm sure it's a simple manufacturing issue, but I'm very concerned that it didn't make it into the quality control system. Once this easily spotted defect is fixed, just imagine what else it can do. I'll try to fix it, but will most likely return it and look for something better. **UPDATE** I received a replacement from Revain due to a filament issue. Arrived in a few days, works fine. Although I had the same problem. I had to take a knife and clean the plastic lip around the intake. Due to careless processing, some plastic parts hung over the metal threads. Knowing the problem before attempting to insert the quick connector probably saved me from having the same problem with the second one. It is highly recommended to check the top of the threads for plastic before attempting to screw in the nozzle. It also appears to be functional and is working well so far. Would have given more stars if it wasn't for the thread issue.
