I've had the Kickr Climb since it first came out. I was waiting on it to be available for quite awhile.

I spend a large amount of time on Zwift, due to the nature of my job and travel, so I personally felt it was a nice to have addition.

I really like the interaction with the virtual environment. I don't think it'll make a huge difference in the overall training aspect by that big a margin though.

Whether it's worth the money is a loaded question, since everyone's version of expensive can vary quite a bit.
