The holes are small but with a little time you can make it quite good. The cable is small.
But very effective!

2 months and it hasn't caught anything, the mosquito was flying in the closed room with the lamp and we were chasing it... and the next day with another mosquito the same thing... it only works as a light fixture.

The mosquito takes its time to fall on the light, but at some point, it will fall. I spent the whole summer with this company and I was the only one in the neighborhood who didn't complain about mosquitoes (in a closed space). CAUTION: you need to turn it on at least one hour before sunset for it to be effective (I used a timer)
