I absolutely love this but the battery life is not very long but the fact that you can use/charge it at the same time makes up for it unlike other bluetooth wireless audio devices.
The charger works great and handles AA and AAA batteries with ease, even at the same time. I have not tried 9V, C or D cells yet, but it looks like they would be just as easy to put into and take out of the unit. The main thing I like is it will charge any brand of NiMH battery I've thrown at it. The fist NiMH charger I purchased (and returned) would only charge one brand of battery.
