I use
Samsung Evo U1 - 64GB & U3 - 128GB, U1 AOK for a long time (> 1 year) still oK, the U3 broke down during a format in JooVuu X for some reason, but I got one new swap from Samsung under warranty
Kingston U3 - 64 and 128GB, both AOK for a long time,
Sandisk U1 64GB, was working AOK in Mobius for a few years, then got locked up, swapped at Sandisk under warranty, and the new one is working great in Mobius for a long time again, however, when I connect the card to PC I get an error message, but when I let the PC look for faults to be corrected, it doesn't find any.
So in short:
Sandisk nâh...
Samsung yes OK
Kingston h@ll yeah....!
Oh yeah, bought me a new 128 U3 Samsung Evo here (Black friday offer) 37 Euro:
Which kind a makes me giggle..... the card cost me more than th Xiaomi Mijia 1080p dashcam I bought last week....
