"May be a little slow"

My Droid Razr runs a little slow, is it because of this card? I can't be sure. What I am sure about is I put this card into my GoPro Hero 3 Black Edition and the video I record comes out choppy. So I bought the SanDisk Extreme Pro 16GB version of this card, and the GoPro works fine now. SanDisk is normally very good, so perhaps I somehow got a bad Ultra card. I never returned or exchanged it because the warranty had expired before I tried it in my GoPro and knew for sure the card was slow. The SanDisk Ultra should work in the GoPro Hero 3 according to the GoPro website, so again, perhaps I just got a subpar card...

"Bought as a gift"

I bought this as a gift for a co worker he went from 512 megs to 32 gigs what a difference. Although it will take him a while to fill it up, he still enjoys it compared to his old one.
