This San Disk Micro SDHC is perfect for today's small electronics that need extra storage, such as smartphones, tablets, and cameras, etc. I've purchased several of these and this brand/version, is among the best. While Amazon usually has great prices on these, make sure you check out sales, especially at Radio Shack, which often beat all others. (No, they don't pay me; I just like to pass along info on good deals when I spot them.) FYI: Radio Shack's sale prices on no-contract smartphones are usually tops as well. I bought my Virgin Mobile Samsung S2 from them and am loving this phone!Back to the memory card, it's so nice to have Android products that take these to expand memory, something the "I" guys could really take a lesson in. And if you don't think you'll need the expanded memory, trust me, with photo-taking and all the goodies you can get, you'll want it over time.As one person commented, yes, this memory card comes in various sizes, including the 32GB version I also purchased, which is the max compatible with the devices I have, although 64GB is also available for the latest tech. All this is amazing to this old-timer, whose first desktop PC hard drive had only 500MB storage!
