I have used this in karate kumite and kata excersices. Works very well.
Excellent product and just as described. Can highly recommend.
I'm very happy with the sport band, I use it very often with fitness, soccer and boxing training.
I bought this band for work, because I can’t wear a regular watch at the hospital. Works well for me, but after one day of using the connecting straps got loose. In the end I got a replacement.
Love it for my workouts and runs!
