NO CUSTOMER SERVICE. Went on twice to notify that i need to exchange defective part. On line it did not give me option to exchange. Only return. Also box kept saying no return for this part. I tried calling four times and no one answers the phone. ( they did send me email right back with instruction once i lft message). Advise what a hassle for a 5$ part. I WILL NEVER BUY FROM THIS PLACE AGAIN UNLESS THEY CAN HAVE VERBAL CUSTOMER SVC.
