The reciever circle - metal.
The adjustable hand - metal.
The connection socket - metal.
The clamp - plastic.

Seriously, the most important piece is made out of plastic. For a $150 piece of equipment I find this unacceptable. Not only it's plastic, it's also poorly designed. You're supposed to tighten it with this little plastic tab that swivels up and you spin it and spin it and then you're supposed to drop this tab down, to lock it down. But the tab adds additional tension, so in most cases you need to pull the tab back up and loosen the clamp a bit then try again. Then you realize you've loosen it up too much, so you have tightening it up a bit then try again. Sometimes you do this over and over again.

So sum it up - the clamping system on this thing is just bad.

Also, I've found that even when tightened down, I can still pretty easily get it to loosen up or rotate around the tubing. I have no idea why don't they just include a normal metal clamp with a butterfly type screw. Basically the same thing that's on the handle itself. Once you tighten those down, they're not going anywhere and there's no guesswork involve - screw it tightly and that's it.

The rest of the system is wonderful. The quick release is amazing, allowing you to unlock your tablet and take it down from the mount instantly. So good. So useful. So well designed. The swivel hand is very good. Strong. Sturdy. Flexible mounting options.

But the clamp sucks and I will now have to buy a better clamp and replace the original one. Normally I wouldn't be this harsh and demanding, but with a $150 price tag I expected everything to be top notch.

Ordered the holder with out ordering the pivot top piece…. Kinda a self inflicted pain but after receiving the piece.. wowza.. works

Very practical and easy to use. Durable and stable. Excellent product.

Nice but expensive.

I’m 6’3” 220 and this works great in a C310. Used with an IPad 8 Gen. I was concerned about the iPad hitting my legs. Non issue. Works and looks great.....compliments my flying style!
