Micro Mini SD Card 512GB, XSRUN Small Memory Card for Micro Mini SD/XC/HC Class 10 UHS-I High Speed Memory Card for Phone,Tablet and PCs - with Free Adapter

I have been trying to write a large number of files to the Micro SD Card but almost every time I write to the Card I end up with a problem. It will say the card is corrupt. if i do a scan and repair it will write a group of files on time but then the next time it will stop writing. It appears that the files are being coped to the disk, but when finished copying, I try to open the folder with the files and it will say there are corrupt files. I can copy the same files to other media and the copy just fine.May be a case of if the price is too good to be true - there is a reason.I would certainly not recommend this Card.

Capacity not what the item was labeled! I returned the product for a refund.

Do not buy false information of what you're buying This Is Not What It Seems bought this went to upload my files into it and then all my files became corrupted it is not a 512gb SD card my computer said there was only 499 on it then when I put it into my smart devices that I had 537 GB on it that does not add up very upset

Worked for a while and then just stop working did not work great stop working did not work after a while after using it for a while the SD card just stopped working

I really liked the customer support. I had a problem and they fixed it quickly! The card is a very good value in the class of 512G micro SD cards. If I need more, I will buy from this vendor!

This is not 512gb, they are 250GB... DO NOT BUY.Wasted 2 hrs transfering data for nothing.

Label on card says 512gb, but actual capacity is 250gb, confirmed on tablet and on PC. Don't buy unless you only want a 250gb card -- apparently I should have read the many bad reviews.

Constantly had data errors. Never able to copy all my files to it.
