    • works
as advertised, strong grip

    • Stronger than expected, very heavy duty for its size.
This clamp is much heavier duty than I expected. Very strong with a clean design. I use it to secure and odd shaped shelf to a wood panel wall standoff so my grandchildren don’t pull the shelf over. Unique application but all the same a real good product that is effective.

    • Good quality, but not perfect
I really like these, I don't feel like it tightens on to a desk or a table properly, it's always wiggling around a little bit but if you have to attach it to some sort of a pole or something like that it seems to like that kind of thing better but it will work on a desk or a pole, I'm not sure why but I think I ordered like four of these or something yet they've come in very handy for various things, if I needed this type of clamp again I would probably buy another one, seems like overall good quality and honestly it works great it's just a little weird one trying to clamp it on the flat surfaces but that hasn't actually been an issue it's hard to get to the point where it's tight enough not to wiggle around a little bit but that has not caused me any problems so far and I've had these for quite a while and used them a lot, I got some studio lights hooked into these and a few other things and I got a couple laying around my room that I grab if I need a temporary clamp. Honestly I really like these and they've come in very handy and they seem very well made for the most part just a little weird when trying to clamp them onto a flat surface ... show more

    • Superb clamp
I was looking for a small clamp to attach my tent to sit on top of a cot. Strange need, I know, but it's a perfect setup while camping. I bought four -- one for each end. These clamps are perfect for what I needed -- to have a small clamp that had a protective coating so that the cloth-to-metal I was clamping would not rip the cloth nor mar the metal underneath. These clamps are small but super sturdy. ... show more

    • Works great!
I got 2 of these to secure a laptop holder. They work great and tighten well. You can tighten them sufficiently by hand, no pliers needed like some other similar clamps. Well worth the price.

    • Excellent product
I have used two of these clamps to hold the arm that supports the overhead panel of my flight simulator since 2016. They are still in place and have not moved at all. This product has all the threads described on the website. Not sure why some say threads are missing. People who say they are small do not read the info listed. The clamps are exactly the size described. This product is strong, sturdy, of excellent quality. I just got two more to hold the support of my F/A 18 C joystick. Flying high with CAMVATE Universal C-clamp! ... show more

    • Nice but a potential headache
They work very well clamping onto the hard backing of a chair and the screw holes are very convenient. I would give it a higher rating but I bought two of these and a Lorell Mesh Headrest together, one of which gave me a headache until I loosened the clamps and moved the assembly outside of my space. I'm letting it air out on my patio, so hopefully it'll be usable in a day or two without causing headaches. ... show more

Review Image by Richard Taylor
I'm delighted. Perfect device to attach a rear view mirror to canopy support on my pontoon boat by bolting a piece of wood as a transition. I think it could have been a little more perfect if the knob which tightens the clamp was a little more robust, perhaps like that of a regular C-clamp. Short of making a whole new bracket from scratch, and If I hadn't found this product, I would have had to return the mirror since it didn't fit anywhere else. ... show more
