With the I-Click you will always click at the right moment because you don't have to look for the clicker. You are practically always on the ball, no matter how you hold the I-Clicker in your hand - with your thumb, palms or foot. Also no longer a problem if you have large hands or wear gloves in winter. An ideal clicker for people with restricted mobility or motor disabilities. The volume of the I-Clicker can vary from clicker to clicker, this is due to production, due to the tolerance of the stainless steel tongue.
