Summary: I bought this for my Blackberry Z10. It arrived quickly and does quick data transfer. I like the design of the card reader - much easier to maneuver than the traditional SD holders. Great price for a great card.
Summary: I recently purchased this for my Galaxy S II. Data transfers very quickly and hasn't had any errors. Card reader was a nice added bonus though I can't say I have much use for it. I would def buy this again, quality Class 10 for half the price of others.
Summary: hold everything and works great. I will say, my phone pulled some weird stuff a few days after putting the card in (I don't think it was related). Anyways I had to take it in and they ended up factory reseting it :( Card works great though, fast and easy, was cheap here at this site
