I put the card in my Mobius Action Cam (extFat) and 'drunk' leave. Everything properly. H2testw shows with complete test over 64GB and no errors in my laptop about 10MB / s write. For my HD Cam perfectly adequate. I've already bought 3 St. - all ok.
Through my carelessness I had ordered an SD card instead MicroSD for the first time by accident. I could return the card as goods shipment and have the money to get credited back problems.
