Not perfect but better than not wearing anything against moscitoes

But mines don't really do much. More like nothing.

These definitely make a sound that was irritating after a little while. It did not seem to have much effect on mosquitos around, but we couldn't use them for very long given the annoying high pitch noise.

I wasn't sure about this product but decided to give it a chance. I gave one to my mom and I carried the other. The only thing I can say is that we didn't get mosquito bites, so we believe the devices work. Yay!

One of them literally didn’t work at all, i.e., it wouldn’t turn on. The other one I was wearing as I watched a mosquito land on my arm and tried to swat it before it could sting me.Edit: when I was sitting in a quiet room, I heard a tiny squealing sound, it was so faint I couldn’t place it at first; then I found it was coming from this device . Now that I can hear the sound it emits, I can also hear that it repeats a cycle of squealing for one second, then silence for 5 seconds. So even if this frequency did anything to repel mosquitoes, it does it only 20% of the time!

I hike outdoors a lot and can use any protection against mosquitos I can. Easy to attach to my bag and have it on without having to think about it.

These don't hold a charge. I keep charging them and they work when I test them after charging but days later when I go to actually use them they don't work

Brought this before a trip to Arizona. I am typically a mosquito magnet, yet I barely got bit this time around. Battery charge isn’t too bad…lasts around 2 days with regular use. Would recommend for a mosquito repellent without any strong odors!
