Works well. I was worried how precise it would be during dawn and dusk. Some others I have purchased left the flights flickering for many minutes.

Have had this for a few months now and it's been working fine. Stable and a good, strong signal. I'm satisfied.

This works quite well for the price.  I use it with and without my monopod and it gives more stability.

Easy enough to install and works as advertised. I took 1 star away as it does wobble on the sides. I put 2 screws in the face of my computer station so they stick out enough that I can put the left and right corners on the screws and the screw heads hold it in place and it doesn't wobble any more. I can just lift up and pull towards me and then lower it to stow it.

Works great at a great price. This is my second one and I expect to get more. It's stable, sturdy and just works.

These pipe clamps work smoothly and are fairly stable.  In use I've found them to be easier to use than my bar clamps because they move into position much more easily.  They are worth more than the lower cost bar clamps because of their stability and ease of cranking.

Nice and simple. This was easy to install and just as easy to adjust. If you tighten the adjoining screw ring enough it holds pretty firm. I had no issues with it moving out of place. If you bump the unit, or pull on a cable, it will wobble for a second, but it doesn't pull it out of position. It holds pretty firm. Overall, I'm impressed by its simple and efficient design.

It was easy to assemble. I was worried about stability with the base as in the picture but It is very stable.

My windshield mount kept falling off. This is very stable and doesn't interfere with my driving by falling in my lap.
