I purchased it to use in sn application that needed it to read a cd card. i tried 3 different cards which were know to be good. Asked to return it snd Walmart dite daid no problem, then store was told it eas s problem, maybe 15 minutes arguing with one associate, and then another finally proved to them i purchased it from Walmart. It had no bar vide on it ire serial number. Walmart website claims 3 hour money return, but return receipt says up to 2 weeks for refund. Called customer service, couldn't understand the broken English of the associate. Requested someone else and eas told i would get a call back in 30 minutes 5 hours ago. Last online order for electronics from Walmart. Guess i may never see my $65.14.
