Here's nice, no-fuss controls, a blocked display, and a fan to cool the device. Now here's what's not so good, no, as the device dances around it looks cheap and feels very fragile. There are no rubber bumpers, the cable is very short and the battery cables are covered in cheap plastic. I have purchased several other Revain automatic chargers at a lower price which seemed to be much better built. Only time will tell if the quality is built into this device.
