The O2Trainer 2.0

MISSING CAP # 5 WHICH WAS RECOMMENDED TO START WITH - A BIT IRRITATING - I WROTE AND WE'LL SEE HOW RESPONSIVE THEY ARE. THE INSTRUCTIONS ARE VERY WELL PRESENTED IN BOTH PRINT AND VIDEO TUTORIALS. I LOOK FORWARD TO GETTING THE COMPLETED MISSING PART SO I CAN START.

Well-built, comfortable, and challenging. I bought it to improve my breathing mechanics and stamina, not as a cure for anything. Bas Rutten's instructional videos are a big plus because they clearly demonstrate proper technique and different ways to use the trainer. I've enjoyed making it part of my morning routine and feel better after using it. I'm looking forward to seeing the long-term benefits with consistent use.

Well made piece of equipment. Good instructions and pictures for getting off to the right way to use this.
