I've used a variety of different training aids over the years, and the O² Trainer is the best.
It's simple and intuitive to use and, maybe most importantly, easy to keep clean after use.
The ease and use of maintenance means that you'll actually use it often enough to reap the benefits.

Excellent product for diaphragm training. Significant improvement over the first model which was already great. The resistance is highly selectable giving you wide options for training style.
