I have been using it with my T-Mobile G2 (Android 2.2) and it works great. I was slightly concerned with this being Class 2 speed, but the original MicroSD card was also a Class 2 from SanDisk and there hasn't been any slowness.
This only worked for a week or two then for no known reason stopped working. I tried it in several devices to make sure the problem was not with my smartphone, and it wasn't. low quality quickly stopped working.
This product was researched and I came to the conclusion for a 32gb micro sd card this has a reputable spot in the many card manufacturers around.
Sandisk also comes with a 5 year warranty on there products!
You really cant go wrong.
I highly recommend !
