I go several times a week to the gym and jogging. In both activities I have my Samsung Galaxy S5 wherever you go. The smartphone fits well into the sleeve and can be also good to use. Bluetooth and Wi-Fi function of course without problems. (What should change it the shell) The weight is well distributed on the arm and the sleeve does not slip or suppressed. They can be worn a long time. The band is good flexibility and the shell fits securely even with large movements and does not cut into. From me strong buy recommendation and for me the best shell for sports.
