I wanted to upgrade my HTC Evo micro SD card. I found this SanDisk at a good price. I have had few SanDisks earlier and had no problems with it. I ordered and it was shipped fast. It comes with SD adapter and makes it usage as regular SD card. I unmounted the existing card from the phone, copied over the contents from one SD card to another using adapter and loaded up the new one. Works great. I didn't see a huge difference in speed, but may be I didn't run any speed tests or anything. I like the price for the brand and 32gb card. I will recommend it.
