It's OK, but not great.
I haven't tested this by firing my gun with it mounted on it yet, but it seems to be of OK quality. Time will tell. I did have a few issues with the product though:
1) I thought the laser would be stronger.
2) There was supposed to be a list of which fitting is for which gun manufacturer, but I looked through the instruction book several times and did not find one. I figured it out eventually, but I thought the installation instructions were a little vague. I accidentally put the fitting in backwards and installed the little E retainer, and when I took it off to reverse it, the retainer had been stretched and I couldn't use it again, leading me to believe that once you fit it for one gun, you can't use it on another without having to get a new retainer (if you choose to use it).
3) What you may not see in pictures is that there's a piece of plastic that sticks off of one of the rail mounts that limits which notch in the rail that the fitting piece sits in once it's installed, and it keeps the black rocker switch that's supposed to go around the trigger guard from getting very close to it. This kind of defeats the purpose of the design, in my opinion. I have a 3.8" barrel XDm, and I have to reach out pretty far past the trigger guard to engage the light/laser.
