he tablet us really good build. M.2 slot helped me to add extra 128G Kingspec ssd. Touch n performance is great. Built in drive performance is good with no heating issues even while running full ASPEN suites for simulation. Battery time is at par with Dell/Lenovo brands. Forced to use Bluetooth keyboard … Touchpad n Keyboard for me stopped working after a week and most likely its some wire in the tablet that got clunky. I have written abt this in Techtablets forum.
