How is it that appliances know just when the warranty is up? The product manual says it has a limited 2 year warranty. We bought it November 2011 and it lasted till January 2014. Checked the troubleshooting guide in the manual and first we ordered a replacement bulb which didn't make it work. Checked the outdoor GFI socket, it works fine. Its not the house fuse/breaker. Only thing left in the guide is the "starter", so we've determined that its broken. As to its performance while it did work, it was on nearly 24 hours a day for just over 2 years and it did its job well. Lots of bug zapping, mostly at dusk and all night. In the last couple months without, we've noticed a huge spike in skeeters! We are buying another one! If the next one lasts as long, that works out to $15 a year in bug control. (if the bulb lasts too) You can spend that in a snap on lots of other ways to kill bugs, so we will stick with this. We already have a spare bulb!
