I HAD PURCHASED A MP4 PLAYER FROM RED-VISION IN MAY 20007 AND WHEN I RECEIVED THE PLAYER IT DID NOT WORK PROPERLY.  I IMMEDIATELY CONTACTED THEM AND ASKED FOR A REFUND OR EXCHANGED, BUT GOT THE RUN AROUND INSTEAD.  I SAVED ALL MY EMAILS FROM THEM AS PROOF!!  BUYERS BEWARE, THEY ARE FROM HONG KONG  CHINA AND SELL BROKE ITEMS THAT THEY ARE AWARE OF WHICH IS STATED IN ONE OF THEIR EMAIL LETTERS TO ME!!  THEY DON'T CARE BECAUSE THEY ALREADY GOT YOUR MONEY!!!  THEY STARTED GIVING ME THE RUN AROUND, SAYING THEY WERE HAVING PROBLEMS WITH SOME OF THEIR ITEMS AND WOULD GIVE ME A PARTIAL REFUND.  I STATED I PAID FULL PRICE AND I SHOULD RECEIVE WHAT I PAID FOR OR AN EXCHANGE!!  THEIR ONLY CONCERN WAS NOT TO HAVE A NEGATIVE FEEDBACK!!  THEIR ADDRESS IS J ZHANG, SHENZHEN JIANSHE YOUJU 001-182#, 518001, CHINA.  PEOPLE WORK HARD FOR THEIR MONEY AND IT IS ASHAME THAT SOMEONE CAN OPENLY STEAL OR HAVE A BUSINESS ON-LINE TO STEAL ON EBAY!  THEY ALSO GO BY THE NAME TRONFY TECH (ZBL) THEY SHOULD NOT BE ALOWED TO SELL ANYTHING ON EBAY!!  I HAD BEEN PATIENT WAITING FOR A GOOD OUTCOME, BUT TO NO ADVIL, IT LEAVE ME TO REPORT THIS MATTER!  AGAIN, BUYERS BEWARE!!
