I had some watches that five years ago I got batteries from here and I had warranty cards to replace the batteries if they died within five years. So of course a week before they expired two of them were dead. I actually found the warranty cards (I can't beleive I still knew where I kept them I sound like a very organized person). I went on down and within 15 minutes they had them both replaced. They quoted 20 minutes and came in under. It was no hassle, quick, and they were very friendly. So why 4 stars and not 5? Well the batteries were close to $50 bucks, but 2 of the 3 did get replaced for free, so that is like $25 each. However, I can go downstairs in Sears and get them done for $14.95 so even without the warranty (they only do a 1 year replacement) this is still a better deal.
