Query: DO NOT BUY - PRODUCT HAS BEEN RECALLED

I bought this charger, and to be honest been quite happy with it thus far (had it about a month). However I just received a letter saying under certain conditions, the charger will overheat the batteries and could damage the batteries and the charger, though there is no chance the batteries will burn or explode.Costco and a few other websites have put up statements and how to return yours if you need to.
