20 years guarantee

An Isokinator is of unusual quality. Every part on and in the device is only made of particularly durable material. But with regular, proper use with constantly increasing physical strength, there will be hardly any noticeable signs of use on the device. Even if you use a magnifying glass. Rather, we are certain that it may take decades for you to discover anything. And that's why we give the Isokinator a 20-year guarantee "without ifs and buts".
