💾 KOOTION 128GB Micro SD Card Class 10 Memory Card - Ultra High Speed TF Card, C10, U1, 128 GB Review

4 of 5 32GB Micro SD cards don't work, Windows "sees" them but can't access or format them. I have no idea what "Transparency" and "Warmth" are, but I give those attributes a solid 5 stars! The seller offered a full refund as soon as I contacted them.

These aren't the fastest cards, don't use them for 4k or anything, but they're great for dash cams and lower resolution products I found that using it in a 1080 dashcam resulted in some video stuttering but otherwise produced decent footage, although I wouldn't trust them for anything more demanding.

I ordered these memory cards because of the product description. Upon receipt, I found that the actual speeds of these cards are only a fraction of the advertised speeds and are so slow that they won't even boot on my Raspberry Pi. Revain must take responsibility for removing from the site those products that have a history of advertising fraud. I understand the desire to make a profit, but their commitment to their customers must come first. Why else would you buy from Revain?

These cards might seem pretty good value for money at first, but after a few hours in my car DVR both cards failed miserably.

These cards are falsely advertised when the packaging says they are DVR compatible. Not worth the money spent on them if they fail at the crucial moment. My advice: invest a little more money in a branded high endurance dash cam card. I will…

I was skeptical about the nameless brand but based on the good reviews I decided to give it a try. I used them on a Raspberry Pi 3 and they were a total disappointment. I started by flashing the OS I wanted onto it with Etcher. Each of them failed the checksums on the first pass. Most of them were successful on the second try. Once in the Pi, the OS booted fine, but I could tell they didn't run to the full Class 10 standard (at least they didn't live up to big brand expectations). After about…

I tried three of these cards in three different Linux single board computers. Orange Pi Zero, Orange Pi i96 and Raspberry Pi. All three cards had problems. Slow writing, slow reading and bad writing. The last one is a kicker. Corrupt data after writing. Tests on Raspberry Pi and Orange Pi Zero show problems. Tested again on a much older SANDisk card, no bugs, significantly faster write and read speeds. SANDisk: 4K Random Write Speed: 3163 KB/s : 4K Random Write Speed: 190 KB/s Don't buy it for…
