Same question I was wondering, they seem to have the cheapest price, BUT it looks as if their tech suppt. may lack as they only provide email suppt. and the website does not look comparable to other brand name sites. In theory, 18.104.22.168 OS's and up should fit 16GB micro sdhc cards but it's how good the quality withstands.
I know that Kingston and Transcend work great for a fact.
