Not great but cheap!

Hello, This is a NON SDcard HC, has a bottom prices. However, this was my first purchase of this product and it seemed to work properly, which have prompted me to buy four more. This really is what can be called the M ****, repetitive clerical error on four copies, one can be happy if we manage to copy 1.5 gigas without error. can not format it differently than SD-format. Yet the thing can fill with zero without problems and answers to the test without error CHKDSK / F Some specific files that copy without problems on an SD other manufacturers, has failed miserably on SDPLATINUM writing. has discouraged serious, given the ridiculous price of the thing I will not get into a RMA procedure that would return me most expensive fees that the gross product values. See other post purchaser for this product, I am far from alone in being disappointed serious.
