Not perfect but pretty good
Advantages: 1. The build quality is really good, the tablet feels nice in the hands, and is comfortable to hold. 2. the 2 operating systems makes it easy to choose what you want, and changing operating systems is easy. 3. the speed of the tablet is pretty snappy. Boot time is low and fast, both on windows and android.
Limitations: 1. the all metal backplate blocks most of the wifi signal resulting in pretty choppy wifi. This is somewhat fixable using this forum post "https://techtablets.com/forum/topic/tbook-10-e6n5-drivers/". I however would suggest just buying a usb wifi dongle and using the usb to micro usb adapter coming with the tablet to have a much better experience. 2. front camera is really low quality looks like something from a 2002 camera. 3. no rear camera at all.
