The key layout of the white keyboard is based on Mac keyboards. The @ symbol is printed on the L button (but is on the Q key if you do not adjust the allocation in Android) and the CTRL key there is also a Command key. The keys are still large enough to longer texts to write pleasant. The keys have a good tactile feedback and can be pressed perfectly, because nothing hooked. The function keys (soft and loud, dumb, "Desktop" view) also operate from the outset with no configuration.
The input is a bit delayed. So the letters do not appear directly when pressed on the tablet. But this seems to be due to the apps and how fast can tolerate inputs.
From me a buy recommendation for this keyboard.
