It just works. Have many SanDisk Ultras and they've been serving their purposes well.

Fast and as advertised. This worked well for my Raspberry Pi 4.

Bought for security cameras hooked up to wifi. Heaps of space, probably more than I needed, but will hold about 6 days of footage, so great if going on holidays

Pretty crap experience Called shop 5 times to speak to someone as u changed my mind and wanted to exchange tv forward Samsung. The phone rang out 5 times. I then called the Good Guys Tempe who picked up their phone and when I explained my situation they said I would have to speak to the Good Guys Bankstown Southey transferred me and the phone again rang out. Called next day at 10 am again same. What type of business does this. Will never buy again at that store.

Handy storage

Works the way its meant too.
