PROS.1.-Bigest memory in a microSD card (64 GB).2.-You have to FORMAT it with a modern device, if not you'll have only 32GB. If you format it with a modern device you'll have 60GB (the 64GB is impossible, or at leats I couldn't).3.-Even if your device says "maximum microSd memory 32GB", this memory 64 GB card can works. I tested on Samsung Galaxy Player 5.0, Galaxy SII and SIII, Galaxy Note II (phone), Galaxy Note 10.1 (Tablet) and on all Asus Transformer. It works fast and perfectly in all of them.CONS.1.- Just the price but you already have plenty of offers. I waited patiently and finally I bought it for $49.9 (incredible!)
