I bought this thinking it would fit our C140 but it's way too "big" for the strut and no matter how tight you fasten it, it wobbles and moves just by hand so much that I haven't deared to fly with it.
The ball mount is also too loose and doesn't tighten enough, it would have been much better with a screw attachment for the pole.

Very disappointed with the product especially since it wasn't cheap either.

The fastening idea is nice and surely works on bigger struts and that's why I give 2 instead 1 star, just beware with the smaller struts.

Almost no instructions and confusing as to what you actually need to install the mount. I had some duplicate parts and I'm not sure what they are for. Also, the screws that screw into the pole are a very loose fit. No mention of thread locker or lock nut or double nuts.
I came away thinking that this mount would not be secure enough for my Insta camera.

The item is well-made, but the packaging and instructions are of very poor quality and not entirely clear. It took a very long time to arrive, and the product does not come with a case for transportation, which is inconvenient given that it has many small pieces. Additionally, the strap that wraps around the placement area is excessively long, leaving a lot of extra material with no way to store or hide it. I’ll likely have to cut it with a metal cutting tool. In summary, while it does its job well, for the price, there are many aspects that could be significantly improved.

Great product secure, stable and easy to set up!

Perfect
