I would happily spend $500 on this if it really did what it claims to. Maybe.

But I find myself a bit skeptical. Would love to see some long-term third party testing on it.

$500 + $15/replacement head. That’s assuming you can even get them. Right now they are out of stock, and my bet is these will never be something you can just pick up at the grocery store.

Any time I’ve bought something with frequently out of stock consumables, it’s been a mistake. It quickly falls out of favor.
