The 1 star is not because it didn't kill mosquitoes (I saw that in the end, even blue LEDs don't attract mosquitoes), but because it broke after 2 years of use.
It may seem like a long time to you, but since it is for a country house and is turned on at night for a maximum of 2 months in total per year, it means that an LED bulb lasted less than 5-6 months.
I'm sorry, but personally, that seems too little to me.

Every now and then, it catches a fly. We're talking about once every three days... For mosquitoes, nothing. What useful thing can I find for it... Oh yes! Good only for a night light, although it's strong... Not even for that it's good.

It does what it needs to do, effectively. Unfortunately, it attracts all insects, so along with mosquitoes, it also catches the rest, unfortunately.

I got it for mosquitoes. The first night it caught one, then it just collected them around it, without going on the device. Waste of money.

Unfortunately, it doesn't kill anything. In a house where we have many mosquitoes, it hasn't killed a single one. In fact, out of curiosity, I would sit and watch it to see if they would go near it. Little flies would enter and they wouldn't be affected at all. It was a bad purchase as it didn't help at all.

Unfortunately, it does not work properly. One of the two ultraviolet lights does not turn on at all, while the second one is defective as you can see in the photo. It has been returned

It worked immediately. Effective for flies and mosquitoes. I would like a longer cord, that's why I'm not giving it 5 stars

Awesome machine. We have been relieved from anything that flies.....(flies, mosquitoes, etc). It sucks everything up. Cleaning is a bit difficult because you need to remove the side protectors and then vacuum them, but it makes them look new. It has been working perfectly for 4 months now.

Good overall

Unacceptable. Compared to other similar ones we have used, it doesn't catch any insects at all. I don't know what the problem is, I suppose it's the bulbs it has.
