256GB Micro SD SDXC Memory Card High Speed Class 10 with Micro SD Adapter(M239-U5)

It's a memory card. It stores things. Dont know if I believe the high speed rating but it did the job for me. Moved files from one PC to the other.

Very disappointed. I started out excited that I had found such a great deal, but within a week of having the memory card in my phone, I noticed my phone was no longer recognizing it. I tried the card in various other devices, wondering if it could be my phone, but they also found no external file when the card was inserted. I feel ripped off, and disappointed.

I bought this just to replace the 2Gb one in my phone. This performs every bit as well as the big name cards. Read/write speeds are the same as with the big name brands, and there has been no issues with malfunctioning, or loss of data like on some other low cost cards. I'll be buying this brand again, every time it's less expensive than a name brand card!

I PUT IT IN MY PHONE BUT IT CAUSED MORE HAVOC THAN I IMAGINED

I bought this To take pictures and video of my vacation. It did not work. Waste of time and money and ruined my vacation picks...

Works pretty good and my Samsung j7. Maybe just enough space for all my pictures

like the size of it for storage capacity

It would not work in my Acer Switch 3. Not sure if it was the card or the tablet as most computer mistake are between the chair and the key board...
