I bought this to replace the practice of burning through disposable AA and 9-volt batteries in audio equipment. The AA batteries charged very quickly (up to 8 at a time), but the 9-volt battery (only one can be charged at a time) took well over 10 hours. If the battery was disconnected or the charger was unplugged, the charge meter on the charger would indicate that the 9-volt battery charge had dropped back to 0 and seemingly reset the charge process. A freshly charged (4 bars on the charge meter) AA battery would also drop back to a partial charge according to the charge meter when it was removed. I could have put up with this, but the automatic shut off stopped working and the AA batteries started overheating.
I specifically got this model because it was supposed to be able to charge AAA, AA, C, D, and 9-volt batteries, but it does not seem to work well when trying to charge different types at the same time. The charge indicator seems to be very inaccurate and the layout of the battery connectors on the charger itself would benefit from more space.
In my opinion, the product would work better if: 1. the adapter was not stowed in the charging compartment, but instead locked into place on one end as it's a hassle to move the spring-loaded sliders out of the way while trying to line up the plug on the adapter 2. the charging compartment itself was large enough to move the 9-volt connector out of the way of the first four AA terminals 3. the automatic shut off worked and the charge indicator was more accurate

What's great about it: Recharges AA batteries quickly
What's not so great: 9-Volt battery charges very slowly, auto-shut off does not work, charge meter resets if the battery gets disconnected
No, I would not recommend this to a friend.
