Query: Break on first use. horrible customer service

The card is corrupt (cannot write/read) on first time use.When I contacted customer service, they didn't even reply to me for a couple day. Then, instead of offer any sincere help. They sent me to page to pay an additional $30 to buy a piece of data recovery software.Worst experience ever. It ruined an otherwise perfect vacation for me.Think twice before buying it.
