I have the RS-Sport and it's been great overall. HOWEVER... the biggest problem to me is the difficulty to get the camera up to my eye when shooting vertical. The screw-on hook attaches to the tripod hole on the bottom of the camera but when you hold the camera while shooting vertical, the hook will be on the right side instead of the bottom. When attached to the carabiner on the Rs-Sport, there's not enough slack to allow you to pull it up to eye-level. You either have to buy another carabiner to extend the connection or never shoot in vertical... :P
