KINESIS Freestyle2 Keyboard, Wired (Pack of 1), Black

In about little over a year, the left hand side of the keyboard became disfunctional. Some of the keys stopped responding, while others typed multiple times on single press. Right hand side of the keyboard is working just fine. Never experienced this in any keyboard that cost a fraction of the cost of this keyboard. Absolutely not worth the purchase. As it has 1 year warranty, no replacement from the company.

At 14k this product is very expensive. By itself It is as non-ergonomic as a regular keyboard. One is expected to shell out another 6k for the accessories to make it really ergonomic, that is tilting in the 3rd dimension. Why is the keyboard sold without the accessory? It is like selling a car without headlights. And they have only a replacement, not return policy.

This was my first split-design keyboard so it took some time to get used to it. I decided to get this one in an attempt to provide some relief to my upper back stiffness and pain. I am a software engineer that works from home, so my keyboards are heavily used. Even though, my keyboards last for years and usually I get new ones just because I get tired of them and want a new look. Not the case with this keyboard. As reported by other users, with a little bit over an year of use, the keyboard started to present some issues like keys not responding or keys typing multiple times in a single press. It is one of the most expensive keyboards I had and definitely the one that lasted the least. I give it 2 starts because it helped me easy upper back pain tension but in my opinion, this product is not worth the price.

The option to keep the keyboard together is good to get used to the layout. I increased the distance gradually and in a week I am typing with very few errors, looking at the keyboard. My shoulder is much better - very happy with it. Really love the copy & paste & undo button. I even dowloaded a software and reassigned one key to have ENTER on the left hand. Brilliant. The only thing is that the keyboard is flat, without the option to raise it (as expected in all keyboards). I use two post it to do it, but it is annoying

it was easy to start on it and so far i'm already very happy with how ergonomic it is. i'm still getting used to layout of the right hand buttons but i really like the left hand shortcut buttons - very useful for someone who works with large chunks of text and has tendonitis! have recommended to several friends already

Ordered this, made sure it was PC and US layout version. Received a "for PC" labeled box, with a "PC US BLK" sticker, PC version instructions but a "for MAC" version in the lettering on the Keyboard, also with MAC keys. Thinking it was a mistake I ordered a second one before returning the first one just to make sure I wouldn't receive the same one. Once order was confirmed, I returned the first one explaining in the comments that I received the wrong keyboard inside the correct box. Return was promptly accepted. I have now received the second order and got exactly the same thing... I confirmed that the keyboards had different serial numbers so it seems it might be on purpose or there is no quality check.

Excellent keyboard. It is taking me some time to rewire my brain because apparently I always typed certain keys (like N, H, Y and B) with the wrong finger, and now when my hands are so far from each other, it is taking quite some time to adjust. After around 2 weeks I am almost back at full speed though. An important note is that this keyboard is almost useless, without the vip3 accessory kit, which includes wrist rests and the possibility to tilt each half of the keyboard, and that was another 60 EUR on top of the keyboard's price.
