Very convenient. Mounted on a monopod Manfrotto 290 series. This tray is large (and heavy) and maintains very well the camera (Canon 600D with grip and lens Tamron 18/200). It is possible to place the camera on a flat surface without tipping forward. Ability to position the camera on the set further forward or backward for better balance. It takes a coin or a screwdriver to screw the bottom of the device. Practical spirit levels. Shipped on time. I never had a problem with my purchases at Amazon.com.
