GREAT , small, and lightweight, very quick charge and does not run down quickly.  Had to have serviced within 6 weeks of purchase as kept shutting down on me and finally would not boot. Had to have serviced by repairman and battery needed to be taken out of inside and reinserted.  Luckily he did not charge an arm and a leg to do this for me, however it should not have had issues this soon--Love it as long as it continues to work!  Crossing fingers, has worked great this full week thus far since having serviced (fingers crossed)
