*My opinions are completely my own. However, I do earn a small commission if you purchase any of these devices via my affiliate links. It does not cost you any more money if you use these links.

Three important things to note:
(1) The interview was recorded using Zoom, therefore the video and audio quality are not great.
(2) The interview was recorded at the end of 2020.
(3) I always try to be objective in any video I make, and Withings did not support me in any way, except for donating their time for the interview. I am also in no way affiliated with Withings except for the fact that I use several of their products.
