Bas Rutten's 02 Trainer - Legit or Snake Oil?

From Amazon:

- It does work, but you drool like an idiot while working out

- Seems like a good concept but I wish it was made out of hypo allergenic material. Whatever material this is made out of caused my lips to rash and crack.

I thought elevation masks were quite definitively debunked? Phone Post 3.0

Wouldn't you need to wear it while you slept to get benefits from it? 

Bas had a post somewhere years ago. He said it's supposed to make your respiratory muscles stronger. No rbc increase obviously. Phone Post 3.0

Abnormally long finger Bas has lol. Phone Post 3.0

Heard Something about the airflow is different than just a straw or tube effect... I forget exactly but something like restricted air in but a full breath out

No it doesn't increase red blood cell production like living and sleeping at altitude for extended periods of time does. It also doesn't "strengthen" your lungs or heart. It's for people who want a shortcut (yet don't get one and waste their money) and don't want to do steady state cardio and/or hill sprints.
