Navision 256GB Micro SD SDXC Memory Card High Speed Class 10 with Micro SD Adapter (256GB)

Just tested this with h2testw and found out it verifies errors after 30GB which would indicate that these are hacked. Returned it immediately and paid the additional cost for a true 256GB card. Don’t let this happen to you.

Fake SD Card. Ran a test using a program called H2testw which writes onto an sd card or hard drive and then reads the information to see how much of it is corrupt or unreadable. The SD card held about 14gb of information and then started losing the rest meaning it is a fake card. Figured it was a scam, but amazon is taking the return so all i've done is wasted time. Be careful out there people. If it's a cheap sd card, make sure you test it before assuming it works. It showed that it had 250gb of free space but it didn't when actual data was attempted to be written onto it.

Went ino my samsung 8 and worked just fine. It holds videos taken with the phone.

This product does not perform well. Periodic pictures that you take including video corrupt frequently and are unrecoverable even with fancy recovery software. You will lose precious photos and videos.

Total garbage!!!!!! Lost all my vacation photos!

It worked but not for what I bought it for.

Had it checked..no errors. Seems to be working fine on my Samsung J7 phone. Much cheaper than name brand SD cards. Monaka name does not appear on card but it works well. Not as fast as other cards but fast, nonetheless. Great value!

All good
