If you have a Ronin S or SC, you need it! I love how versatile it is and that I can attach so many things to it. My only issue with this is that since the inner metal part sticks out as much as the rubber, it scratches my Ronin, but I fixed that with tape and also that the logo is on both sides. I would have liked the logo to be on one side so my grip accessory would have more stability, but it just means I have to back out the screws more.
