Read all the reviews and really did some research before purchasing as my husband returns almost everything we get him. However he was really suffering w his chronic still to be diagnosed knee issues and I just needed to him to try SOMETHING beyond physio etc. All the points, tips and instructions were bang on and my husband has really appreciated the support for hockey. The K1 Flux has provided him more stability and support when on the ice, which helps after (particularly n etc). Lots of interest and questions from other players.
