Had the Fenix 5S until the battery life went. Very happy with the 5 except the music feature would cut in and out when running. The 7 solved the problem and music works well. Touch screen and added tracking of performance values is also a nice addition. Some reviews complain about not being able to see the screen on the Sapphire very well. I have not had much of an issue with this. I also like the S being not so large.
