It's a Kingston MicroSD card at a fast speed with a large capacity. Nothing else need be said BUT if you want a review, here it is: What were have here is not failure to communicate but it is a lovely little 32GB MicroSD card complete with adaptor (to add to my now large collection).

Very versatile can swap from one device to another easily

As described! Great service!

I've been using this since I bought my Galaxy S7, and it is awesome. I had some corrupt files going on, but I think it wasn't from this one.

writes 63mb / s o read 78mb / s, so can not complain Presis :)

Kingston Technology came out with the DataTraveler HyperX USB 2.0 Flash drive back in February 2008 and at that time it was one of the fastest portable storage devices that money could buy. How fast was that?

The card easily hits over 19 mb/s for Read speeds and a little over 11 mb/s for Write speeds, which is more than enough to handle any HD recording your might be doing. If you need more space, 64GB is the largest capacity available right now and you might as well get it from a reputable company like...

Performs well above specs; Decent overall performance; Large capacity

Not the fastest in terms of write speeds
