After getting my brand new HTC Desire HD I discovered it only came with an 8GB micro SD, so I upgraded to this one at around £14, which works out as about a GB per £1. I've come to trust Kingston over the years as one of the best, if not the best, only rivaled by SanDisk.
Good price; good transfer speed; seems reliable
Might want to wait until the 32GB models decrease in price
