128 GB Micro SDXC Class 10 with Adapter for Samsung & Most Smart Phones

Originally had issues with the Galaxy S5 recognizing the memory. Had to put it on the PC to reformat. The memory did not worked well in my Samsung Galaxy S5. Noticed it took excessive time copying pictures and videos into the memory connected from both to a PC and to the S5 device via USB. Then it did not read all data, pictures or videos once the micro SD card was installed in the S5 device.

I purchased 2 of these 128 GB class 10 micro SDXC cards. I was unable to successfully transfer zip files or backup of Note 3 Roms to either. After the transfer,they were non-functional. I can't tell you how many times I reformatted them and still the same result. I also was not able to create new backup of the Rom. I wished I had spent $30 more for the Samsung cards.

Card worked for few hours then was no longer recognized by my Android phone (HTC One). It would no longer mount. Sometimes I'd be lucky and I'd be asked to reformat the card, which failed each time. I tried to format on a PC and on a Mac: in both cases, the card is not recognized as being inserted.

After 2 days installed in my Lumia 830 I am getting a bad sd card message from my new phone.

Bought it as extended memory for my Samsung S5. So far it works great! I bought one for my wife who has the same phone, she loves it! It really gives you endless possibilities with your phone. Highly recommend it!

This item worked for about one hour. It eventually stopped working all together. It also was very slow. I would not recommend it to anyone.

Purchased to use with new LG L3 smart phone as memory card. Have been using about a month. No issues.Would use seller again if needed.

It doesn't work.... waste of gas money
