I recently purchased the Lens Coat for my GKJr. Katana Pro to provide additional protection for the Gimbal. I chose the black cover to blend in with my other camera equipment. While I have not used either the GKJr. Katana Pro or the Lens Coat Cover extensively, they both are fairly new, they both are very well made with high quality materials and great engineering.
The Lens Coat fits very snugly, provides great protection for the Gimbal Body, and does not impair the operation of the knobs, the level, or the view of the base plate hash marks.
Great Job!! ProMediaGear
