I previously had a Samsung phone, was really easy to transfer everything over and have hardly noticed operating difference. The ruggedness of the Cat phone is great, have already dropped it a couple of times and no scratches or cracks like previous phones I've had. Battery life is amazing, I get 2 days out of each charge without a issue have even done 3 days between charges. I wish these where available a few years ago with the FLIR camera would have used it heaps through my trade.
