They're the size of the connection box, they don't make noise, I just plugged them in. We'll see in time if they really work, so for now they seem good to me. :)

It works, happy with the repellent, since I live in an area with a lot of mosquitoes, the truth is super calm and without worries without mosquitoes when sleeping and being at home

I arrive in very good time, they look good, I am already using them, I hope they are very good, thank you very much
