Good day. I want to ask the users who own the HRM-Pro Plus, if they have a problem with the quality of the elasticity of the strap? It happened to me many times with Hrm-pro (not Plus) that the strap slid down my body during hard training. I had to solve it by shortening the strap, but again during a new activity I felt that my chest was being squeezed. I did not notice this problem with older Hrm dual or Chinese Magene models. I found them more comfortable. Since I complained about Hrm-pro, I am thinking about Hrm-pro plus. Thank you for your answers
