Where to begin.
Build quality. I do not know if these guys change their CNC bit every one of these they churn out, but I cannot find a machine mark on it. It's obviously machined, but, you know how you can see machine marks on most machined parts? The only place I could find any evidence of manufacture is where the 19mm rods run through. And they're recessed, so there's nothing rough that will ever touch your rods. It's solid as a brick. With a good chance of success.
The anti-oops easily releases, and the locking mechanism is brutally strong. It is metal, folks. 99% metal, anyway. Glides so smooth, you could use it as a mini dolly. Has 15mm tube support, which is critical for the big-lens movie types, as it fully supports standard 15mm lens supports, or if you need a mount for your matte box.
Has plenty of slot length on the plate to accommodate darn well near any movie camera I am aware of, and all the way down to mirrorless and DSLR setups. You could even put a point-and-shoot or a GoPro on this if you wanted to let things get out of control. Of course, they include a pair of both 1/4" and 3/8" mounting screws. This is a very well made, heavy-duty piece of gear and it should work with just about anything you can imagine. This is my 2nd piece of ProAim gear, and I'm sure it won't be the last. I highly recommend their beautifully crafted equipment.
