Z10 Workout Case / Armband combo?

Hey all,

I have more of an accessory question here for my Z10. I have my Z10 in the Case-Mate Tough Case (which BTW, saved me from one of those :eek: slow-mo moments where my phone decided to jump out of my hand down to the ground) and wanted to pick up a workout arm band.

I was looking at the Arkon Sports Armband and it looked to fit the bill. Anyone have any reviews for this product? Any reviews for another workout arm band that works well with an encased Z10?

Thanks!
