Replying to Binding inserts? (Binding freedom)

Hey guys wondering if anyone has had experience with binding inserts. I was thinking about buying all the tools you need to install and a couple sets of inserts from binding freedom. I know they aren't too easy to install precisely but I think I understand the process. It's pretty expensive tho. It just seems really nice to be able to swap bindings around. Specify I want to be able to swap jesters and shifts on my Whitewalkers.

Anyways, any good or bad experiences with inserts?
