easy to use
perfect balance
resistant of accidental dropping

Rarely do I fly my Steadicam without my Zen attached. The precision and accuracy is phenomenal, and calibrating it right after I've found my perfect balance is a breeze. Though I'm not always trying to keep it all green and centered up because ether shot will demand otherwise, I still love having the visual indicator in my periphery (I mount mine below my monitor with a custom 3D printed bracket) because it helps me understand the exact movement that my sled is going through or where it is in space without having to rely on visual indicators on the monitor. The pan function is really interesting but I haven't found a use for it yet. I've already done a software update through the USB-C (which can also be used to power the unit) and it's super easy, gave me new features! The customization on how you can display what axis or axes, or G-forcd even, and define the sensitivity and format of display and everything. So much packed into this simple little rectangle, it's my favorite!

Attached right into the cheese board I had on the underside of my camera rig. I was able to add the extra weight to it balance out for my flycam support vest.

Solidly constructed out of metal with an adjustable quick release collar. The low profile ProBoom locks into bracket. To detach the ProBoom you simply press a button on the end of the mounting bracket. Fit is perfect with no play between the ProBoom and bracket. Even though there’s no play the movement of the ProBoom is smooth with little resistance.  

I was also pleased to find that this bracket fits the Herman Miller monitor columns as I already owned two. The Herman Miller columns have more elegant table mounting options too.

A must have if you own a DJI ronin

I bought a few of these because I needed small weights to help counter-balance my BMPCC on a motorized gimbal. With a decent cage around my camera, these weights were ideal as I can mount them in any -20 thread and get the results I need. Due to a threaded hole on the opposite side, I'm able to use these to mount exterior accessories slightly higher when needed. These are pretty ideal for more than their intended purpose. I also like that they're only 4 ounces each (most other counterweights are a pound or more, which was way more than I need).

Does what its supposed to

I'm using these with my Ronin-S. I attach them with a small cheese plate to the back of the Ronin-S' camera plate and it allows me to offset or move forward my Sony X70 far enough to operate in underslung and flashlight mode clearing the rear motor assembly.
Props to Josh at Make Art Now for the tip.

I found it as expected. Serves the purpose perfectly.

used this on the end of a selphy stick to help stabilize an LG 360 cam. I use 4 and my videos have smoothed out significantly.
