 Correct. So talk a little bit about that, why it makes sense to do it at a level where you're getting professional advice and you're being fitted and shown how this, because I could have never figured this out by myself. Right. Well, it's a little bit of a double-edged sword. Something is better than nothing, over the counters, a gateway to better hearing. I would still rather have a patient try something and get a taste of what it's like to hear better. That's well and good and fantastic.
