UPDATE: the seller has relisted the item
The new link is:http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=151336209900
I bought two and used them with my gopro hero 3+ black in 4K, protune etc without a problem
It doesnt come in retail package but looked absolutely new and worked well for m
Yes there are cheaper 64GB cards out there but they probably have the standard 10mb/s writing speed which is not good enough for recording high res videos with gopro hero 3/3+, while this card has a writing speed of 45mb/s
I bought two of these, loved the cards and the seller so far. The seller seems to be relisting the deal within few days of it being sold out so keep an eye on the seller's items.
