Bought one from Aliexpress back in Jan. 2023, mounted it on a 9mm pistol and it was working fine on the first 100 rounds. It started to turn dim on the 50 rounds right after, the dot disappeared and would not turn back on. I let it rest for a short while and it came back on by itself after I pulled back the slide and let it spring forward a few times. It's not normal and I'll have to keep it eye on it the next time I go to the range.
