Bests & Worsts Reviews from Amazon

We are only two days into using our Zap-its, so I can't testify for endurance. But so far it has been fantastic! Both units (medium size) charged up quickly and held the charge throughout several long periods of mosquito purges. I am very pleased with the performance as we snap, zap, and flash our way through insects. The sound and visual special effects are rewarding revenge for being the target of previous bug attacks. Fights on..... UPDATE: We really like our zappers and use them on walks with the dogs and while doing outdoor projects, but.... so far they have not lasted. The units charge and the LED light works, but the grid will not energize. You can light them up but no kill. Not even a sizzle! The first of our twin pack quit working on day 10. I used the lifetime guarantee info included with the zapper to notify them and had a new one in two days. Fantastic customer service, but then other zapper gave up the following day (day 13) and when I contacted again via their warranty instructions 6 days have gone by and still no reply. I guess I used up my warranty quota. I contacted Amazon for replacements and will receive another twin pack in days. I'm hoping it's just a bad lot. We really like how effective they were on black flies and mosquitos. Now the deer flies are becoming bothersome and I'm "out of ammo". Please just last 1 season and I will be a happy camper! Heck, at this point lasting a month would be great. A great product, now just give them a longer life!
