this is a really cool product expecally if you hate flies its bit of a challange to get a fly that has landed but it the air its not so bad and fruit flies they get fried with one wack. they main problem i have found with this is if you try to hit more than one fly at a time it does not work and the battery cover keeps falling of i have to use furnace tape on the handle and remove it when its time to change the batteries but im still glad i bought this one i may try the other one that uses the c size batteries that will show them flys but this one does a pretty good job
