I have had this for right at a year. I love it. It's really important to have it at least 25 ft from where you are, however I have it attached to my deck. It really does keep the bug population down. I live about two miles from a lake, and I get millions of mosquitoes. Millions. I love to BBQ and grill out and having this has helped me reclaim my backyard experience. I have 4 bug zappers - 1 Flowtron, two rechargeable stingers, and a plug in stinger. This thing attracts and kills everything that's going to annoy you at night. And yes, it does attract mosquitoes. I don't know how since scientifically mosquitoes are not attracted to UV light. I clean it out periodically and there are tons of mosquitoes in the grid. I also like that this company stands behind their products. I recently had an issue where my grid quit working. I emailed the company, the next day sent me an RMA number to send back to them - they fixed it and sent it back. Plus, it's made in the USA which is a major plus for me.
