The wheel has a little less than the resistance of the device (but seems solid ... even a check in time)
Only regret very big (but I think the original grip has the same defect. Toujour I bought a grip with my devices (I am on the 7th or 8th) to have the unit under control but This grip has a bump down, which causes the grip is too short a few millimeters A highlight for me.. the device is ultimately more stable horizontally without grip for my hand (little finger completely below) It is therefore likely it stays on the shelf, in the end (but I think the grip Canon has the same defect, after the photos)
See the use ...
