Purchased this to go in my HTC phone to increase it's memory capacity. Does exactly what I need it to do. No problems. Only reason I didn't give it 5 stars is because it's a memory card, and saying "I love it" would be too strong.
Fits really nicely in the palm of your hand (and I have small hands). Responsive and comfortable. Only reason I gave it 4 stars is because it's no use to my other half whose left-handed (but I knew that when I bought it - ;-))
