I saw an ad for this on indigogo, and I was wondering if they function like they advertise that they do. It says you can adjust it to a sweet spot, where a light equalization push will equalize you ears and a harder one will compensate your mask so you can freedive hands free. anyone try something like this? does it work consistently? does it work at multiple depths? is it more trouble than benefit?
