Easy to install, works as advertised giving you a bunch of length adjustment. Also impressed with the build quality of the heel plate.
I use it with the older TR race and it works just fine, but I had to dremmel off ridges on the toe shim to get my TR toes to sit flush. I assume they align properly to the Gara Titan toe pieces. I also really like the built-in crampon adapter on the toe shim.
