Here's a review for anyone interested: https://techtablets.com/cube-iwork10-ultimate/review/
TL;DR The Cube iWork10 Ultimate is a good alternative to those looking for an ASUS Transformer Book style two in one. Or something similar to the Chuwi Hi10 with a slimmer better metallic build. You get a great build, Android 5.1 and Windows 10 out of the box and one of the best 10.1″ keyboards I’ve used with two USB 2.0 ports.
But it’s not perfect, if you must have full USB 3.0 speeds then this isn’t the tablet you’re after unless Cube fixes this issue. And the speakers just aren’t loud enough in Windows.
