    FYI – I rec’d the 2nd replacement Sanyo dual camera yesterday and it seems to work like a new camera. I really appreciate your customer service. I don’t understand how to brand new cameras could be defective. However, that has nothing to do with your service. I can only speak well of your organization and even recommend anyone buying from you. Thanks Mr. D. Russell Mr. D. Russell
