Super impressed with this adapter frame. This isn’t cheap plastic, this is a solidly built aluminum grame and you immediately feel the quality. There are quality, non-slip pads on the inside that not only help it grip, but protect your OSMO as well. Simple to install and simple to remove, even for my old, arthritic hands. The quality is what sets this apart from other products. Bonus: Aluminum is strong, but also lightweight. It's nothing to toss this into the backpack.This provides a direct mount to a standard stick or tripod without any other adapters. There are 2 “fingers” on the sides of that which you can flip out and suddenly it’s transformed into a GoPro mount. I love how they tuck out of the way nicely without taking up any room. There’s a cold shoe mount on the side. When you install this, you can still access the SD card without removing the cage.When attached, you get solid, wobble free shots. I have a plastic case on my Osmo, and it almost fully closes with this still attached. LOVE IT!At the time of this review this is listed at $23.49 and worth every single penny. Great value, and great tool for the bag.
