I purchased batteries for our camera from them. One of the batteries was defective. I was given a USPS call tag and I know they received it. They were supposed to either replace this expensive battery or credit me. I tried numerous times by email and phone to follow up - they have never returned a call or email since. I would not purchase from them again. They do not honor their guarantee or service promises. They owe me money or a battery which I doubt I will ever see.
