Well designed and easy to use. I especially like the clear display and detection of bad /unrechargable batteries, although it's a pity it only detect bad batteries by pairs, not individually.
However the name "Intelligent Charger" strongly suggests that it also has other advanced features like automatically detecting charge level and charging accordingly. it does not, it detects the Amperage and charges for an appropriate time. However you can't really expect all that in something this price.
It's still great value for money, just don't expect it to be as full-featured as the name suggests.
EDIT: I would not charge batteries with different Amperages in this at the same time, as the lower pair are liable to be overcharged and higher pair undercharged.
