Watch Me Cad , Breathing Trainer

back with Watch Me Cad #2 this time I'm working on a breathing trainer concept that I got from seeing those ads pushing them . This design was made in a vacuum and has no input from others on the market other than the job they perform. Any likeness to an available product is purely coincidental and I will not be marketing the finished product for sale . I will however post it for free when I'm satisfied with the final product.
