Not really much to comment on as I have had good experiences with SanDisk Ultra in the past. They are a little more pricey than some of the other brands but only by a couple bucks. What you get is &#34;no surprises&#34;. They pop into your phone, camera, tablet and basically work forever. I don't run speed tests so can't comment on whether they are plus / minus milliseconds faster than another brand (a millisecond here or there really is not a big deal to me). I've never had a failure with a SanDisk product (or Kingston, another good value).I used it for awhile in my Asus Tablet but currently it has been moved over to my Droid. Works as advertised a was an excellent value.
