Hello first, I think here I need not say much. The device is simply brilliant. The volume, that I know of old equipment is no longer so disturbing. On television one must of course already set the volume a little higher. I have placed a very light and not sloping headphones from Bose with exelentem sound experience (without cable). Now my body weight and my blood pressure drops has been peaks and my pulse falls already under 50. If one way is still working in a real rowing boat on the water, you have your life expectancy increases significantly already. Do not forget, if time allows, it is better to work almost every day on the water, of course, surpasses all. But I do not have to the time, you can not stop at any time on the water.
