I used it so often that the battery connecting terminals snapped. They were not made of spring steel in the original Super DeLuxe zapper. I got many hours of use out of it - about 3 years of zapping almost every day.
Now I zap everyday with the F-scan2 and I supplement that with the plate-zapping.
btw: the new Super DeLuxe zapper has the spring steel connectors
