What's the most you would spend on a real mouthguard cleaner?

Like the title says, i'm curious to find out what's the most you would spend on a real mouthguard cleaner.

What is a "real" mouthguard cleaner?

You drop it in, press a button, and it cleans your mouthguard better than any toothbrush scrub or denture tablet ever could.

I've been looking for a better way to clean my mouthguard, but it seems there's a lack of it.

Wondering if anyone else feels the same.

Let me know your thoughts.
