In view of many disappointed reviews, I entered this morning in the pool with no fear evil. And yet, no complaints !! The reader was ensconced under the cap and strap glasses, he did not move for an hour! I practice crawl and back crawl and I have not hooked once, and the atria remained perfectly sealed. It will change my life because I was seriously starting to get bored by doing lengths. There I did not see the time passing and looking forward to start again, it's so motivating to swim to the beat of music or Dragons Pirates of the Caribbean! = P
