The tool works perfectly. It does the job. There were no problems with sticking nails. The only thing I don't like is that the light is useless. But that's not why I bought it, I bought it because I don't care about the lifespan of the compressor. Now I would like to add that after owning it for over a month I had a moment when the gun would not fire. The solution was to take the battery out and put it back in, and strangely it worked. There was a separate incident when I had a misfire. The gun fired, but nothing fired. All I did was take the supplied Allen key and remove the tip, it was actually easy to fix the misfires. But I want it to be a simple clamp instead of fiddling with screws. Still 4/5. So far I've been very careful with this tool.
