@phaus any improvement to your wrists with the Ergodox?
If I had the discipline to keep my hands up with a regular keyboard I might have the same results.
Another thing to keep in mind is that it will take longer to tell for sure my wrist pain comes and goes.
I don't have tendonitis, however last week I was typing with the top of the keyboard much lower than the bottom and there was a feeling of relief in my hands. Just putting this out there.
