. The charger is small and lightweight and very quiet. All you here is the air going in the charger on one end and coming out the other end like a cool mild gentle breeze on hot sticky summer night Lol. The touch screen with the stylus pen works smoothly. Very easy to work. The charger has alot more bells and whistle then I thought. It has like a graph chart and data on individual battery cells, and to much to list. The only down side to me is when the charger is done, you can barely here the beeps to let you know that the batteries are ready. If your in the room, like you should be , with no TV or music on... then you can hear it. NOW if your like me, I like to play on the computer with the TV on but the sound down and the music playing in the back ground, you really cant here it at all. Overall, for my self, this is a wonderful charger for the price!
