Insulation Guard

I literally have no idea if this little rubber pad is good or bad or why it is so expensive as a retrofit part. What i do know, is the aF4 is directionally what the hobby wants. Programming needs to be more versatile, cleaning far less complicated, and numerous other "wish list" items. However, the aF4 has achieved a baseline where every other wannabe has failed. For that, I am very grateful this aspirational product exists.

It was easy to install and i believe it will help keep the interior of the unit cleaner and easier to clean too.
