These units are sleek, light weight and easy to carry around.  I purchased 2 of them for sales people to use and 1 had an issue turning on after a day.  I made 1 call and Tom from IT Replay shipped a new unit overnight.  When the new unit showed up I left it to charge over night and had an issue with it not recognizing the battery.  I contacted Tom, who apologized and shipped a new battery overnight again.  I plugged the new battery in and BAM, good to go.  Tom's customer service was absolutely Top Notch!!  You just don't find customer service like this now-a -days, but he was a customer service champion!!
