Finally bought this when Carrefour is selling it at $49.90 (as opposed to the originally pricey $79.90). Also bought 2 Rayovac 1600mAh NiMH batteries to make a set of 4 (with the 2 free ones).
Excellent charger. Really lives up to it's name, charging all my batteries in slightly under an hour. And it's intelligent, I accidentally tried to recharge already-charged batteries, and it cuts off after 5 minutes.
Batteries which are not completely depleted charges in much less than an hour. Handy when you want to "top up" the charges.
At $49.90, it makes it a MUCH better buy than the Sony 1hr charger, which only charges 2 batteries to 85% charge in 1 hour. The Rayovac is a true 1 hour charger.
