At the 6D I use instead:
"Comfort genuine leather hand strap for Sony digital cameras, etc. - With metal eyelet for strap" not taken, so I am fully satisfied and have it for months (except briefly today to test content). There, I guess the width and rigidity of the band, comfortable to hold and stable even with NEM 70-200er lens.
The Peak Design Band is now on the NEX-7 and OKisch. Just a bit too expensive to a cheap-feeling for any band. Just my personal opinion of course.
