Great fun, but accidentally bought the same yellow one which I think might be warning them off rather than attracting them to the wholesome goodness of 1,500 volts.
Mine does ~1000v. The trouble with them is you have to swipe at the insect pretty sharply to catch it in flight, a bit like hitting a tennis ball, and in the process you sweep all the best china/ glassware off the table/mantelpiece. I've also found that even if you do manage to hit a fly for example, there's every chance it'll only be stunned, and it drops to the ground only to rise again and fly off a few seconds later! The best way to use them is to trap a fly against a flat surface such as a window or carpet, and hold it there for several seconds while it fizzes and sparkles.
I once used it against a large blue bottle which got catapulted across the room from the electric shock but it didn't die. There's something about "current kills" which might explain it.
