it is a good card

I have two of them from two years ago.

70MB/s read, 55MB/s write, and very good random speed too.


The price has not come down much. Still relatively expensive.

Depend on your need if it is worth it.

Cheaper at Amazon UK

Cheaper at Amazon on a lightning deal, https://www.amazon.co.uk/SanDisk-Extreme-microSDXC-Frustration-Packaging/dp/B013P1M436/ref=sr_1_2?s=computers&ie=UTF8&qid=1472554181&sr=1-2&keywords=sandisk+64gb+micro+sd

Class 3 speed ?

32mbit/s for 4k? Maybe on a phone, I've just checked my Panasonic LX100 and that's got a U3 card in it because 4K on that is 100mbit/s. A U1 card in that didn't cut it, gave me 1080p only. Sure that's kinda excessive but on the other hand there's no battery power to do a h.265 encode on capture and even if there were a high bitrate guarantees you're capturing everything without artifacts.

I have used these cards to shoot 4K in an adapter on both Sony A7RII and Sony AX53 and they work perfectly.

That's simply not true.

Thanks OP I have same card paid a little bit more a few weeks ago.

The OP's Deal reminds me of a similar one some months back here:
