This thing is a tank! Heavy, with almost all parts made of tough steel, and featuring multiple mount options including Arri style mounting holes for avoiding unwanted pans and shifts.The cup itself is very large, lots of surface area to hold on to your clean, flat surfaces. It features a magic arm with said Arri mounting sockets.The includes action-cam and smartphone adapters are the only plasticky parts in the box, the rest is rugged and could, I think (don't take my word for it) securely hold something heavier than a tiny action camera.My only beef, and I was hesitant to take off a star for this or not is the actual suction mechanism which Is a button on the side you must pump a number of times before it grips the surface. I have encountered this type of mechanism before with disastrous results - the button would slide in and out with no effect - and I had to discard an entire cup from another brand.Mind you - THIS ONE WORKED and the suction on my mirrored closet doors was SO STRONG it took me some effort to dislodge it! That's good news for your gear. Whether the pump will last and resist I can only guess - time will tell.In the meantime, this product is way above any of the generic suction cup mounts I have seen before!
