Hi everyone! There is my reflex ball which was presented by my ex. Item is a set from 3 varicoloured and different in weight balls. Also kit includes headband and an elastic band which attached one from the balls in front of the athlete's face. The main aim to use it is developing a reaction to strike. This simulator replaces the need for shadowboxing. I use this set when I need to go on a business trip and I know that I won't have time to walk around and look for gyms. Such the kit can be made independently thanks to the video on the Internet.
