After three weeks of use with the EOS 7D Canon + 17-55 (total weight: about 1500g), I am fully satisfied with this strap. The weight of the unit is very well distributed and does not feel any discomfort or fatigue even after a full day spent with the camera hanging from the strap. The Reflex is at hand (adjustable strap + two stops to stabilize the position of the device when you do not take it in hand) and the strap knows to be forgotten when it comes to quickly take a snapshot. The foam that is at the level of the shoulder is thick enough for the weight I have to carry. Beyond that, there are chances that the strap is felt in the neck and leaves marks on the shoulder. Fixing the Reflex looks very solid and leaves a great degree of freedom. The only complaint with the strap on the left side, the clip to open the strap is available to people behind me. To discourage theft (you never know), I had to block this clip (totally useless, let's be honest) with a cable tie.
