The i-mate 810-F handset has passed vigorous testing which allows the manufacturers to offer it with a lifetime warranty
Handset manufacturer i-mate’s 810-F is so tough the company has given it a lifetime year-on-year warranty. That’s because it has already put the 810-F through a grueling set of tests and trials, including running a car over it, immersing it in all kinds of fluids, kicking it, dropping it, baking it, freezing it and even calling it bad names – and yet the device continues to work. I-mate says the 810-F has even passed the rigors of US Military toughness specifications (standards as referenced for impact resistance, crush force, submersion, rain/mist/salt, fog, dust ingress, and vibration).
