Thanks, ordered one.

Total was NZ$39.50 include shipping.

Ordered the 128GB version which came to NZ$72.87 including shipping. 

Anyone tried these cards?

I either use them for Raspberry Pi (or similar) and want good 4K random read/write (good for phones/tablets too). Benchmarks here.

Or for my video camera, which needs high enough sequential write speeds for 4K video and burst photos. (Sony A6300 camera which I've read can be hit/miss with various cards.)

I've had my eye on these since release, they're priced competitively.

they were even $1 cheaper today, $18.99

I bought one for $18usd, but then bought a bunch of other stuff as the increase in shipping is negligible. 

Got a couple of those anker indestructible lightning cables. I am fed up with apple lightning cables which seem to have a 100% failure rate after one or two years.
