TERRIBLE!!! No customer service, although there is a phone number and e-mail address, they just don't care to respond. Nowhere in the ordering process was it mentioned that their "warehouse" is in China. I've been waiting over a month for a cable I ordered. I'm disputing the payment with my credit card because Martgreat couldn't be worse!!! DO NOT ORDER FROM THIS STORE. I wish I had looked for reviews prior to ordering, there are lots, all terrible. This is about the Yahoo Store Martgreat. Should be NOTgreat. Buy elsewhere or not at all!
