Since I always had a stick in my pocket, I was looking for a durable copy. The Kinston R30G2 I stayed then hang. This stick has now been through a lot with me. He is already 10 times like me determined on the ground (among others on concrete). Once even from 2 meters height. Nothing happens to work as the first day. Dustproof I can also confirm. Apart from the rubber housing is no mess determine until today. Waterproof I have not really tried. But if he is in a small puddle of water, that's no problem. As far as I can confirm. Transfer rates are absolutely fine. Have not measured, but super for normal use. I would buy again.
