Review on 💾 Bundle of PNY 16GB Performance Class 4 MicroSD Flash Memory Cards (5-Pack, P-SDU16G4X5-MP) by Wendell Chapman

These things are real SBC junk, I've tried and tried to get them to work and even if they did once booted in blue on the moon, they did nothing on subsequent boot attempts. They don't seem to have a problem with saving files or anything, but they refuse to download DietPi on my Pi Zeros or my Odroid XU4, so I'm inclined to say you need to look elsewhere if you want them do something. made with SBC. They're good for data (as far as I can tell, I'll at least have to do more testing to say definitively that they are), but not for loading.
