MEH! Yet another retro handheld
Why so many buttons? It looks like you're just slapping a Sinclair logo onto yet another one of those cheap-ass chinese retro handheld, while removing the ability to emulate the dozen of other 8- and 16-bit platforms.
You really need to provide other incentive than just a big bunch of games which you could download of WoS anyway.
Also, with the recent release of the Recreated ZX Spectrum Bluetooth keayboard, it's a sorely missed opportunity not to support Bluetooth, which would have allowed to do a bit more than playing games on this gadget.
Lastly, what I would really expect on such a device is an Atari joystick port, so you could plug an authentic joystick (my two favourites were the Competition Pro and the Konix) and retrieve those lost sensations.
