"My son only experienced a little discomfort (was a little achy) the next afternoon. He said he only had a little ache in the calf at the end of playing cricket on Saturday (he batted really well and made 40 runs) he also bowled 6 overs so was very active all afternoon. He did trampoline on Sunday without discomfort. So I think you’ve fixed whatever it was. So thank you. Best money spent ever!!"
