This review is from: The Official Bas Rutten O2 Trainer (Misc.)

I bought the Bas Rutten O2 trainer instead of the high altitude trainer. I am very impressed! This O2 trainer is very high quality. The unit is made of a high grade polymer coated in a biodegradable rubber housing. The mouthpiece is sort of a snorkel or scuba design and is very durable. There are two ways to use the O2 trainer: with your workout or with breathing exercises. The trainer has an intake on the right and an expeller on the left. The intake can be adjusted with different size diaphragm screens. Workout screens are 14mm through 5mm; breathing exercise screens are 4mm through 1mm (very challenging). Bas has an online tutorial on his website that explains everything about the trainer: how to change the screens, what workouts to do when using the trainer, ect. This is the only trainer I have found that works your diaphragm as well as increasing your lung capacity and anaerobic endurance. The entire case is less than half the size of a high altitude training mask and fits nicely in a book bag or gym bag. The shipping is very prompt; I had it in 4 days. Deserves six stars but I can give it only five!

Training with both tools has allowed to elevate the intensity of every workout beyond any routine on its own.

The quality of my workout is increased which has increase the my athletic performance levels. I have noticed a faster increase in my speed, power and endurance by using both the O2 Trainer and Mass Suit.

Training without them in game time scenarios have now slowed down allowing me to focus and get "into the zone" easier because my physical wind and strength levels are above and beyond normal.

Thank you!

After using for a month The O2Trainer has not only helped me breath easier, it's helped me run faster, trainer harder, and fight longer.

I started noticing a difference a couple weeks after I first used it, and after a month I really noticed my endurance had significantly shot up. This is definitely something I'm going to recommend to my friends.
