Good build quality. It will trap some of the mosquitoes in the room but never all. Therefore, you can't say that you will sleep peacefully. The noise is light but noticeable.

I have it here for 7 days. Yesterday I tried using it on the balcony for the first time, at night with just the extra light from my phone. It didn't catch a single mosquito even though there were several (since I am on the ground floor and there is a garden right outside). So, the following test was conducted. We left it on all night to operate in a closed room (0 lighting) of 9 square meters and in the morning when we checked, it had caught one mosquito. In the end, there were at least 4 others inside the room that disappeared using the fly swatter method. Yes, it may be cheap, but it doesn't do the job. It's better to spend a few extra bucks for something better. Maybe the very low UV lighting is to blame for not attracting mosquitoes.

From my personal experience, I can say that it did catch some mosquitoes along with other insects. It may be more effective in other conditions with more mosquitoes. It has a soft UV lighting and the fan is barely audible, so it is also good for relaxation at night. Just be careful not to drop it from a height because it is all made of plastic and the fan may detach and stop working, although it is something that can be fixed
