Underwhelming compared to past koozies
I have wore out my two previous Duff koozies.  I found this and thought this was a great deal.  It's an okay deal.  My issue is that the quality seem very lacking.  The black liner inside the koozie is so thin that you can easily see through it.  I've never experienced that before.  The novelty is great but I think I would look for alternatives.
