I have had the same class 4 16gb for the last three phones I have had.
I use Kingston have never had issues with them.
I even took it out of my amaze and piped it into my Verizon work phone so I could have music, piped it back into the amaze no issues.
Never had any microSD fail.
I recomend Kingston 32gb class6 .
