The Single-Button Quick-Adjustable ARRI Rosette Handgrip from LanParte allows for lightweight, one-button control for quick 360-degree angle adjustment. It replaces annoying adjustment steps, saving time and providing a better shooting experience. The dual 15mm rod clamp with rosettes is compatible with all 15mm accessories. The extension arms with ARRI rosettes have a cutout design that eliminates unnecessary weight. The nonslip silicone handgrips offer comfort and stability.
I originally bought a set of yellow Ikan handles which fell apart within two weeks of heavy reality shooting. I returned them and swapped them out for these Lampart handles which turned out to be amazing - very strong, comfortable and won't slip. I highly recommend.
Works great in the traditional setup as an over the shoulder option, but can also be setup to be used as a turret. See pic below. All the is required is to place the attachment hub directly under the rig's center of gravity and you have a pretty neat narrative tool.
