I've got a Chuwi Vi8 which would be similar- there's a first impression review on here somewhere.
The amount of RAM appears to be the rate limiting issue, as in Windows mode it's always claiming to have run out of memory (but continues to run fine) and the RAM might be at the root of the Bluetooth stuttering issue"
The screen is, in my eyes, extremely good, particularly in Windows mode. Battery life is good, but not spectacular.
But, that sums up the whole tablet - good, but not spectacular. I want to like the Windows Mobile format and the tablet has been good for trying it out, but, goodness me, it needs more quality apps.
