Does anybody know of a reputable case that is "sealed" and water/dust proof? I would like one that covers all ports on bottom, including speaker cutouts if possible. I operate a component saw, and any other case allows a lot of saw dust in those ports. I've seen a "spider" brand "waterproof case" but it has issues with the fingerprint scanner apparently. Any suggestions on a reputable brand, alternative to OtterBox that "seals" audio/charger cutouts?
