I bought this for using my camera while cycle touring. So that I could pull it out and put it away one-handed (on the odd times on an off-road cycle path to take a quick photo while riding). It attaches to the handlebar and stem easily and securely, the padded inside makes the camera safe, the one-handed pulls work very well. I took one star off because it's not waterproof - though I didn't expect that it would be, with the closure system. It's 5 star for what I needed. (I put the camera in my handlebar bag when it rained).
