Esteem hearing implant

I have recently heard of a new hearing implant. It is called the Esteem Hearing Implant. From the little I've been  able to read, it sounds amazing! The website also explains how it works.

Here is a video of a woman (Sarah) when her Esteem was first turned on:

My confusion was in how clear her speech is. Apparently, she just had really good SLP's and has always had pretty clear speech.  She explains it here:

Like a hearing aid, she can still turn it off (like her husband snores and so she turns it off at night).

This costs $30,000 per ear. (much less than a cochlear), but insurance does not cover it. If you watch the video, you see that Envoy (the company that makes Esteem) paid for Sarah's second ear and paid her back for the cost of the first one.

Let me know what you have heard about it.  It sounds like a miracle to me!
