I use this in my bedroom as I wake up in the morning with bites on my neck and back. I average around 20 mosquitos in my apartment, put it on my bookshelf, zapped the mosquitos and fruit flies all within a few hours, so happy! No more bites and buzzing in my ear waking me up in the middle of the night! Very lightweight and quiet, can't even hear the bugs being zapped. I'm buying another very soon for my back patio. Highly rated and very AFFORDABLE! Thank you!
