Cougar200k arrived last week. Just tested it in few funner rr's.
It's great for typing and have some great additions. For example, by pressing "FN+Q" you can change frequency of keyboard. 1x, 2x.. (test it by typing long text and erase it with backspace.. it will do it by different speed. It's possible that could be helpful ingame for faster response too)
But tbh, not very satisfied with cursor keys. Even tho it's great to be able to rope without any kind of keylock or other known bug, cursors are important for every rope scheme and they just feel weird on this product. Tried friend's 200k and it didn't seemed like that at all. Now i see why lalo and daina weren't satisfied.
Gonna give it few more tries, just wanted to write first impressions.
