This one worked for me and every night it caught three or four mosquitos that had previously been buzzing around my head. Some notes from other reviewers that I agree with - if the mosquito is in the room when you are in the room, this product may not work. However, when it is dark and there isn't anything else to attract the mosquito's, it did work. I would usually run it for a few hrs in the evening in my room before going to bed, or in another room all night after going to bed and keeping my door closed. Over all, it worked surprisingly well.
