KINESIS Freestyle2 Ergonomic Keyboard w/ VIP3 Lifters for Mac (9" Separation)

Fantastic! have high sensitivity in my tendons from past carpal tunnel and bilateral tendonitis injuries.

The product is really good. Took some some days to get fully adapted to the new configuration, but now i can see how uncomfortable was the previous setup.The positioning lemme adjust my shoulders position, I’m no longer feeling them tired in the end of the day.

I tried a competitor but found their keyboard too large. I don't need the number's pad so this Kinesis keyboard is a great value. I've used their keyboards before and they last forever. Happy customer.

Update: another side effect of the ESC being too far left is that the number function keys (F1, F2, ...) is misaligned with the number keys (1,2,..) just below it -- exactly one key off -- making it very unintuitive!------First, the upside:In general a good design for a split keyboard. Material is fine. Split distance is sufficient. The ergonomic is good. I use a Macbook only with USB-C ports, so I like the additional USB-A ports so that I can plug in a mouse. I like the Mac function keys (volume, brightness, window manager, etc.). I enjoy using it for the most part.Now, the downside. None of these have not been mentioned by other reviewers, but I'd like to reinforce them so hopefully the manufacturer can consider the improvement.From the most significant to the least:1. The major downside is that the lifters don't live up to expectation. Someone else has a video showing how unstable they are. A person like me tend to move the keyboard around the desk a lot. That's bad for me. The concept is attractive, but maybe they can't engineer a robust solution under budget. I end up just taking them off. I feel I overpaid for an unused feature. If you really need an angle, I suggest you use a tape to fix the lifters so they don't swing.2. The placement of ESC is TOO far away for programmers.3. The placement of number 6 can be debated.

The clip that holds the two keyboards together arrived broken. It seemed that this was a known defect with the keyboard as the broken clip was outside the plastic packaging of the keyboard itself.
