How do you like the removable jaws feature now that you have used them for a bit? I usually shy away from such tools preferring to buy permanent jaw type in general. Especially in snap ring pliers...

They work well. You just need to be sure they are fully seated. It only takes a few seconds to change them out for whatever your doing, and the case keeps them organized.

Back when I was doing a lot of automotive work, I wanted a set of the iWise type as they do the Metra and Deutch connectors. with the insulating rubber vs having to do the crimps separate. I may still pick up a set along the way for some other things I do, but for the majority of what I do now, the Klein work well.

I have a couple iwiss (I think that's what you typed before spellcheck, checked you?). One for ferrules and one for Deutch connectors. Work very well. Ratcheting action as Keith describes on his multi crimper. I really like the Deutch connectors for automotive work.
