Immediately upon opening the box you can see how beefy this thing is. The rubber and metal is thick, the ball arm has a robust knob and a spring to lock it down. I think just about every part of this is made of metal except for the rubber base and the pump button. The ball mounts have an extra ring of rubber to keep them tightly locked. There are 1/4“ and 3/8” screw holes all over the base to add accessories. There is a hole on the base to add a cable or cord if you want an extra level of security between the base and a mounting area. The whole design was clearly not an afterthought, they put some time into making a quality product that has a lot of versatility and usability.The suction seals very easily and sticks extremely well. There's no way to pull it off without intentionally releasing the suction. The air evacuation pump to create suction works really well and I really like that there is a white line on it; if you see the white line, it is an indication that you should add suction.If I could improve one thing it would be a bigger mounting plate on the camera side or a mount that would be Arca-swiss compatible. The camera mounting plate is pretty small, which is perfect for small action cams or for the included phone mount, but for larger cameras it would be less shaky if it had a larger surface. As it is, it would be easy to add one to this existing design by adding another mounting plate or getting one with a built-in ball mount (these are 20mm diameter balls) so I'm not taking off any points for that.
