Very Nice Unit

Took a little longer than promised, but well worth the wait. Charged a batch of batteries very quickly and with good information displays. Happy with my purchase

Pretty nice charger

I charged up my Li-Ion batteries and was quite impressed by all of the information "read-outs" that I could observe as it was charging. All very useful information etc. So far the charger works very well.
