Big surprise, they were put two of them on display this afternoon.
The Aura is small and light, that's very nice. It's really close to a Mini Glo

The two-finger scroll works well and as opposed to what I've read in one review (maybe the two guys talking non-sense) it doesn't only move by 10% steps. I didn't notice some defects on the light layer, but I wasn't paying attention to that.
The back is nice to the hands.
I couldn't find the refresh setting and with some dim light surrounding I didn't see the diamond pattern (unless the diamonds are teeny tiny ones).
That's all I could notice in less than five minutes.
