Have been waiting for4 months for a different 4GB flash disc that works. Fred did send me a 2GB one - which works , but it is not what I bought and not what I paid for. He will now not take any of my calls - have tried numerous times. Am totally disgusted with him. I did give him the benefit of the doubt and gave him a chance to replace the Sony Flash drive that did not work, but he has not kept any of the numerous promises that he made.
