I have had nothing but bad luck with 4Sevens, their customer service is great but my luck with their lights isn't. I had two mini123 's sent them back and ended up buying a Fenix PD20 and its been going strong for almost a year. About a month ago I decided i wanted a pen light and would give 4sevens another try. I got a Preon 2 and it was sweet... until it fell from my pocket to the wood floor and stopped working. Now its on its way back to Amazon to hopefully get a refund. Any one else experience these problems? I ask because I never see much negative about 4Sevens. First post by the way, been lurking for a while and finally decided to join, Howdy from Texas!
