It's an excellent bit of kit. I've used it both on 12s and 13s and provides a lot more confidence compared to any whip I've used.
I've never owned the previous version of the tool so can't compare to be honest.
The previous version is only for cassette which is the soles jobs but limiting (especially with track cog) now including track, BB and ebikes chainring which is a boost.
