Hooshion Aluminum Alloy Mount Plate Adapter Action Camera Clamp Adapter Clip with Counterweight Holer Compatible with DJI OSMO Mobile 5/4/3 for Gopro Hero 8/7/6/5/Osmo Action

This product does work. I was skeptical after reading that it would not in the answer to a question. The device is solid and is HEAVY with the camera. You have to tweak it to make it use full. I was able to attach to my Zhiyun Smooth 4. I also had to add some extra weight to the gimbal arm. This was necessary to compensate for the overall weight of it with the camera. See the picture! So I have kept it instead of returning and am satisfied with it!

 Love the quality of this product, work on my gopro hero 9 & there nothing bad about it. If you plan to purchase this product you need weight to counter how heavy the go pro hero 9 is, im using the dji osmo 4 and its working it ass off to balance it.

Good product but in accurately described, does not work with DJI osmo Gimbal.

Probably a little heavier than I needed. But it will work.

If you remove the weight and reverse it, you may be able to balance your Hero9 (I got it to do so once out of many attempts), but it is so heavy that my Osmo mobile 3 struggles to lift it. When it does do so, even when balanced, the back of the weight bashes against the arm of the Osmo 3, regardless of the direction in which the weight is mounted on the end. The Mobile 3 definitely isn’t designed to support the Hero9 and this weight. After researching, I discovered that the Osmo3 has a max payload of around eight ounces. This weight and the Hero9 together weigh 12.7 ounces. On the other hand, this is a very sturdy weight system, if your gimbal can handle the payload.

Well designed, fits hero 9, adjustable weights, they did not cut any corners on this.

Using gopro 8 and DJI omso 6. As mentioned by others the fumble can’t handle the weight of the GoPro and the holster. Unfortunately can use with our other larger and will be returning to try and find something much lighter

This is essentially a counter-weight to a GoPro, allowing your shots to be much smoother. This is machined-aluminum, which is nice. It’s just very good quality! The build quality is almost sexy.
You can adjust the balance by sliding the counter-weight up to about a half inch. That does give some wiggle room. It does not seem to be balanced for a GoPro Max 360 – it’s just a tad heavy, but it’s not necessarily intended for that. But you can buy extra weight for the Max 360, so that’s moot.
