SanDisk chips are pretty good but relatively expensive at times.You'd think that online prices would be more affordable. It can be but you can Not tell if the seller is selling a fake product ot not.The one I received was genuine. Any of SanDisk products can be returned and exchanged for another if genuine so I've not had a problem in exchanges with the company **knocks on wood**!The 32gb version works well with Android tablets but not the 64gb versions so beware. I did read online at other forums that the 64gb version works relatively well, though, with Android phones, which is weird.Why would it work on the smartphone but not the tablet?Prices have dropped so it may have come down in prices at local retail stores so do shop around.
