Perfect small sized clamp with lots of clamping force and huge plus having 1/4 threaded holes ready to go for other attachment's making this extremely versatile. this is a must have!

I bought it to mount on an e-bike for a pocket camera and it works very well. It's rock solid. I will share one thing that I learned in mounting and pointing the video camera: first install the screw rod and tighten it first, then screw on the camera onto the rod and point to the desired (front) direction, turn to tighten the red nut against the camera bottom. In tightening the screw rod, wrap the screw rod with a rubber sheet before tightening with a plier to avoid damages to the thread. It works well with a horizontal handle bar; however, if you had an angled bar, you might need a ball joint adaptor in order to point at the front direction without tilt. The turn leverage bar may be a bit long to get in the way of other mounted items, I used a rubber band to hold it at the center so that neither side protrudes too much.

It’s definitely well made, the only caveat is that it’s hard to get whatever you’re clamping to face in the direction you want it to. It’s either too loose or you run out of threading and the clamp is pointing a few degrees in the wrong direction. Maybe I’m just stupid and don’t know how to solve this problem. But it didn’t exactly come with instructions. So I’m dead in the water.

This is a nice strong product that clamps up tight. I use it primarily in conjunction with my Sioti mini ball head. I haven't had this clamp long, but I find myself reaching for it more often than I would have guessed. I've clamped it to the steering wheel of my car to take selfies. I've used this clamp as a window mount on my vehicle. It adds a nice bit of low light stability to what could otherwise be an awkward hand hold. (I use a piece of nesting material to protect the glass and though I believe it will hold, I always keep a protective hand on my equipment using it this way). Since the jaws on this open to 54 mm (2.125 inches) I was able to get some nice fall color shots this past weekend, clamping it to a limb and the end of a picnic table.Will this clamp replace a sturdy tripod? Of course not. But on those days when you simply want to take your camera on an unencumbered stroll, this isn't a bad companion to have in the pocket of your coat.

I purchased this unit because I needed more clamps and just did not want to spend on a few superclamps at around $30 a piece. My main use for the clamps is for off camera speedlight placement. I usually use the heavier and sturdier and more pricey superclamps. After purchasing 2 of these units, I liked them so much more for my particular applications that I ordered 4 more immediately and diched the superclamps. These are lightweight and solid (for a lightweight item), more compact and easier to carry. I just screwed on the coldshoe for my speedlights and Im ready to go. I've even gotten extra screws and attached the triggers to this thing as well, it comes with many threaded holes to give you more options where to attach things.I would not put a big studio flash on this thing (that calls for a superclamp), but for my speedlights and audio recorders, this things are so much better.

I was generally surprised at the quality for the money. This is a solid well-made piece of kit. Everything works as it should and it is very versatile with three different places to put the 1/4" screw which came with it. They even included an allen wrench to adjust or remove the 1/4"-20 screw. I order a similar one at the same time hoping to get a good one between the two. This one was far superior in every way and detail and I immediately ordered another one.

The clamp itself is good quality. However, there's no way to tighten the mount on a camera if you need the camera to point in a certain direction. You can use this in conjunction with a quick release, like https://www.amazon.com/dp/B01K9TKFTM, but in that case, you can save a few bucks and get the version of the clamp without the camera mount.
