This replaced a Stinger brand 80 watt Bug zapper bought new the previous year that didn't last longer than 20 days. Started with one tube, then a loud pop and the whole thing quit. Sent it to the manufacture and they told me it was hit with a surge. I don't see how, it was plugged into a surge protector. So I got the Flowtron, bit more pricey but it survived the entire summer without a problem. And unlike the Stinger brand, this does not clog up. Best of all - it's AMERICAN MADE!!
