First, the processing is top and the flapper also looks significantly better than the low-cost versions.
BUT, the cheap versions of the electronic fly swatters work in my opinion much better. The difference seems to be that here probably a current pulse is sent and current flows in the low permanently. The effect is in this version: It bangs neatly loud and the fly (or even other insect) is thrown away a piece and is stunned briefly. Either one is fast enough for a 2nd use the swatter or fly is gone. Under favorable clap the fly will speak at the Grid "stick", which makes escape almost impossible and you can dispose of the fly comfortably.
