Recommended microSDHC

Use a high quality brand. Sandisk isn’t the only high quality brand. Sandisk cards used to be very expensive, however now in the US  they are close in price to other high quality brands. If you plan to buy a 32GB card though, I suggest you get one sealed in a retail package(not loose or bulk) from a reliable vendor as there are many fakes and defective cards around. You should check Amazon and other places for reviews of the various cards before buying.
