I like the charger, well worth the price. I replaced my old $60 smart charger, with three of these. The old one was too picky about which batteries it would charge, and which it rejected. I'd occasionally have to pull out a cheap charger, to get them started. The IGO charger, if it refuses, the battery is really dead.
These chargers, are slow chargers, not battery cookers. Definitely a good thing for NiMH batteries. Only thing missing, is a discharge cycle.
The alkaline batteries I've gotten, and used, haven't fail yet. No leaking batteries, and still functioning. Regular alkalines, that I've experimented with, do eventually leak, after 4-5 charges. The Kodak batteries bought on Woot, are the worst offenders. Pretty much stopped using the regulars, since I've got so many of the IGO batteries now.
These are 1.5 volt batteries, and I have a few devices that don't last with 1.2 NiMH. These work great in my Metal Detector, which takes 8 AA.
The charger is a great buy, the batteries are a decent bonus, although I haven't had to throw any out yet, and been using them since last spring. You will save money, if you been buying alkaline.
