What do you think of this case? It's $26 with shipping on witglobal.com
More expensive on Aliexpress (around $45).
It's supposed to be suitable for the ZT-180 (278x185x25mm), the Flytouch2 (267x17.5x14mm) so it should be ok for the G-Tablet (210x140x14mm).
I think the keyboard is made of silicon (to be confirmed) so the screen will be well protected. With a Bluetooth mouse, it could be a nice laptop!
If somebody already tried this, a review will be really appreciated!
