It is very useful

Great product, can't fault it.

I've used this in a raspberry pi since October and it's been great. Previous cheaper cards have failed in shorter times under the IO stress.

I bought one of these previously for a raspberry pi 2 and it works mint. However this time I bought one for a raspberry pi zero 2w and it flakes out at different points, that said, it does similar things in raspberry pi zero w and raspberry pi 3. PBTech seem to be too busy to email me back with suggestions. Kingston website recommends these cards for RPI.

Good value for money if you are looking for basic backup
