No noticeable difference
I tried this while skiiing at high altitude and could not tell any difference at all.
I would not recommend this for people who need to count on an oxygen boost for health conditions.

Not for do it yourselfers
I wasn’t impressed. I was never able to get the Z wave paired with Samsung. Paired to other deadbolts the key mechanism is very sensitive to screws being too tight or too loose. The unit is heavy, so the installation has to be extremely tight
