Apparently my Im very hard on my things. I finally convinced my wife to let me get a dna mod after 4 years of going through 2-3 Chinese cheapies a year, but it needs to be durable (shock proofing to survive falls, no low grade aluminum that gets gouged), ideally stainless steel, American made (so if problems arise I can call and talk to the guy who actually made it and generally have better warranties), ideally water resistant (my hands and clothes are always wet from work), and user serviceable battery. Thank you
