while i was waiting for the OEM one, I used for a month a ”leicke sharon keyboard”
It’s really cool, and the touchpad it’s large and very usable (more than the OEM one).
also the charge last for a ton of time.
BUT it’s a bluetooth keyboard (once paired, it takes no time to connect: i used it also to digit the PIN loggin windows, cause it connects immediately when the tablet turns on.) and it doesn’t provide a ”dock” or a stand. so to use it you need a cover for the tablet which can hold it up.
I’d take the sharon in consideration if you need the use of the touchpad and the stock keyboard one isn’t enough.
(after a month of use, i gave it back to amazon because i preferred to use the stock one, but i still regret that touchpad. it was like the one of my 17,5 inch laptop, same feeling.)
