Good for me and not so good for bugs. I like that I can drop it in without getting my hands sticky. I like that the bugs are stuck and I don’t have to see them.
Easy to dispose of, just open the machine and dump

American 110v plug so not able to use in UK 🙁

It works good, but it's NOT 100% effective. Light on it could be brighter, or perhaps a fragrance to help attract insects

The product is working. I live on the bay and have terrible mosquito issues especially after a lot of rain. I needed to do something. I set this up and immediately began getting victims in the cage. After reading some other reviews, I think it is important to clarify how this thing works. It reduces and eventually eliminates the population in your 1/2 acre. It takes a little time to do this. So if you set the machine up, turn it on and then wonder if it works because you just got bit by a mosquito, you are misunderstanding how it works. You will still get bit as long as there are mosquitos in the area. But keep the thing running and you will get bit less and less until eventually there are no more around to bite you. That's how it works - it eradicates the population. Plug it in and leave it running 24x7. Don't move it. Don't turn it off when you're not there. Just leave it running in the same spot.

The proof is in the cage.

Michigan summers are full of mosquitoes and other flying insects. I keep this plugged in and it zaps very well. June bugs are best since it zaps for a long time. While my wife doesn't like the zapping, I like it for keeping the flying critters at bay.
