This card is great. Ive noticed slight improvement in every aspect of my phone. So much space! Very pleased. Came on time. Brand new. Easy to open thanks to Amazon. And it mentions on the tiny booklet that this thing is temperature resistant. Thats a big plus since overuse of smartphones tend to heat em up pretty good. Being from Texas, the heat out here only makes em hotter. And my last SD seems to have fried. Well this is a good buy. If i need another i'd definitly buy again. Maybe the black and gold one. It only available in 16GB but its super fast.
