Marrs Communications is an online scam. I've ordered Nakamichi cassette belts and other parts, and received and paid for the invoice from Krista, the owner of Marrs Communications. I waited for one year, but she never sent me and she have not been responding to my e-mail letters. After I realized that it was a fraud, I began to find out there are other victims in the U.S.A. and other countries. Marrs Communications took my US$93.75. I lost more money for wasting numerous hours for writing so many e-mail letter and making international calls for one year! She takes advantage of people using rare high quality cassette decks. Marrs Communications will not ship paid products to the customers.
