We purchased this back in April since summer starts early here in Florida. We really wanted some protection from all the bugs at night when we sit on our patio. This zapper really works. It's been over 3 months since we got it and it is still is working wonderfully. We have had no issues with it at all and we run it nearly every night. We have it hanging several feet away from our sitting area and it keeps the bugs away. I know we had an issue with our outdoor power outlet about a week go and had to get it fixed, so we had to go a couple days without our zapper. We were getting attacked by bugs constantly. This is such a great asset to us. Makes a huge difference. Love it.
