Roger was kind enough to pick up a SINTECHI adapter for me in the UK, and I have been playing with it here for an hour or so now.

It seems to behave just fine with a 4GB SD-Card, and with a 16GB SD-Card, but not with the 64GB card here. I don't have anything in between 16 and 64GB to try it on, but I suspect some kind of capacity limitation.

EDIT: The onboard chip is labelled as FC1307, but also has a letter A literally scratched onto the surface after the FC1307 part. So it is either a FC1307A, or a counterfeit of some sort.

If anyone at the Meet has a 32GB card for me to try, I'll report back on that later as well.

Cheers
