My Mosquito Magnet broke -- again --, and this time I got tired of spending a fortune to get it fixed. After reading reviews this device looked great, and so far I'm quite happy with it. I bought 2, one in front of the house, and one in the back, and I keep them on all day. Every evening at dusk, you can begin to hear the mosquitoes getting zapped. A beautiful sound, indeed... Like the Mosquito Magnets, you can't eliminate ALL mosquitoes but it makes a big difference.
