Pros: When it worked, it charged the batteries well.

Cons: The screen is dim and hard to read.

Overall Review: I used this sparingly (charged approx 2 AAs each month) for 11 months. During this time the charger worked well. However, after about 11 months I plugged a battery in and it wouldn't recognize it. I disconnected the power, let is sit for a while, and then plugged the charger power back in without any batteries installed and was disappointed to see "done" flashing for each battery location (despite no batteries being installed). I called Powerex's tech support and the guy told me that the charger needs to be replaced. Luckily, it has a 3 year warranty so I just had to pay for return shipping...but I'm hoping this isn't a sign of how unreliable the charger will be.
