This keyboard is fine for lower tenting angles.
But for Higher tenting angles, You'd want your alphabet keys as close to the OUTSIDE edge as possible.
That fact presents a challenge on this kinesis, because of the gaming key placement on the left edge and the special keys on the right edge.
Overall... the concept is in the right direction, but it does not cover all basis as far as being Ergonomic..
The neutral resting angle of ones wrist is approximately 70 degrees.. the goal is to get as close to that as possible..
On this board.. if it was tented to the nominal 55 degrees, as is possible on split boards of this thickness.. The alphabet cluster is too high up, which would force you to use quite a large and tall wrist rest if you'd want to reach them..
The included wrist rest will not operate at high angle either, because it's flat in profile with the board, so had you tried, your hands would just slide off.
And the problem with that is, if you have a wrist rest that high up, NOW those outside keys are really difficult to reach, because your wrist must turn against the wrist rest to hit them..
Even the Enter Key would present a challenge if using higher tenting angles..
This keyboard is a half measure towards being ergonomic..
