I had an issue with mine and the finish flaking off, but Ivanko took care of it. Pretty standard pressure ring collar otherwise!

Classic competition collars that have been around a long time. They aren't fancy or shiny chrome like a lot of them now, but they work well. No real purpose for a home gym unless you just really like them or want everything to be comp specific for training. Other cheaper collars work just as well too

I have used these at the public gym a couple times and when spotting and loading at a meet once. They have a very specific use in powerlifting. But unless you are in a comp or have a kilo set up at home I don’t see the value In these.

Neat to own but I never actually use them. Unless you compete in powerlifting and want to be comp specific, no real need for this type of collar

I use these and I don't compete in powerlifting. I do have an extensive Ivanko collection so these fit the vibe.

A classic powerlifting competition collar. You would never have a use for these if you don't compete in powerlifting though. They are pretty expensive as far as collars go, but they do weigh 2.5KG and they really are specific to competition. My one gripe on these is the secondary tightening method has a tendency to get locked up on these and its really hard to get that loose once it's locked up. It's probably mostly user error from gym members doing dumb things with these.
