Nora? Anti-snore device

Just saw an add for 'Nora'. It senses when you snore and adjusts your pillow (it has a bladder that inflates). Curious if anyone has heard of any success stories with it.

I have never used it, but wanted to check it out.

After looking at this, it seems as if your head has to be in a specific location for it to work. Too far up or down on the pillow would change its effectiveness. Then...if you are a side sleeper or prefer to sleep on your stomach it might be uncomfortable.
