Review on Kinesis Advantage2 Ergonomic Keyboard KB600LFQ by Hideo Tsuchida ᠌

Different pros: Ergonomics. Just what you need if you have problems with your wrists or stoop when working with conventional keyboards. Allows: 1) Straighten your shoulders by dividing the keyboard into two blocks. 2) Comfortably position the brushes. Thanks to the concave shape, there is no need to move the brush to get to any of the main keys. 3) The thumbs are more involved. Its cons: Price. On the one hand, it's expensive. But a functional analogue, taking into account the assembly time, will not be much cheaper. Quality. Rubber bands instead of normal F-row keys (fixed in Advantage 2). Thin plastic case, everything rattles (corrected by pasting with biplast).
