I recently bought QIDO (qwerty in dvorak out) from keyghost. It arrived yesterday, the one I got is white colour, Patra from Keyghost have agree to exchange for a black one so I will post it back to keyghost latter today. Just want to do a quick overview of the device.
Right now I don't have any keyboard that have number lock, so I can not test the numberlock function, which lets you toggle between qwerty and dvorak instantly. I will try this function later on.
I have attached some pictures and a video.
The QIDO also failed to work with my Filco 87U brown cherry, but works fine with Filco 87U blue cherry.
