Pros: - Price
- Very size efficient
- Individual channels
- Shuts off when batteries are fully charged

Cons: - At 300mA charging current, not really a "quick" charger (takes 10 hours to charge 2 depleted AA batteries)
- Capable of charging 4 batteries at a time, but can only charge 2 batteries of the same type at a time (2 AA and 2 AAA)

Other Thoughts: This is probably the most inexpensive smart charger that you'll find. It's small and lightweight, making it ideal for travelers. The only downside is the charge time. It takes 10 hours to charge depleted 2300 maH AA cells, and it will only charge 2 at a time, so if your device uses 4 AA batteries you won't be able to charge all of them overnight with a single charger if they are 100% depleted. I haven't tried AAA batteries yet, but would assume charge time to be in the 3 - 4 hour range for 900 maH cells. If you have a unique need to charge 2 AA and 2 AAA batteries simultaneously or your recharging needs are somewhat infrequent, this charger is ideal. Otherwise I would look at SKU 6194, which is a much better charger (at a higher price).

Bottomline: This is a good charger, but be sure the limitations detailed above wouldn't make it impractical for your uses.
