Review on Adjustable Tabletop Aluminum Rotatable Standard by Duane Mejia

with dual camera and improved phone holder). Ease of installation. Can be attached very well and firmly to the table. I used for the webcam. The adjustable height is 15" to 25.5" as stated, to which the included flexible ball head can be attached. After receiving it I wanted it to be a little shorter at the lowest. But that's the size they advertise with detailed drawings. So no complaints. I didn't use a phone holder, but it has mounting nuts on the back and one side for two orientations. It has one side with a spring extension to grip the phone. By measuring I'd say the width is closer to 2.75" x 4.25" if you're really using a lot of spring tension. at 2.5 inch the spring is not engaged. So the image is closer to the right than the entry that says 2.5-2.9 looks like how I see it. But look where the picture measures in between (points beyond where the phone sits). There are only two disadvantages: 1. The bottom rod/tube is attached to the table/desk clamp with a rivet. This allows you to move around a little. Because the bar is so tall, it has about +/- 0.25" of swing at the top when fully extended. I fixed it by drilling out and piercing the rivet. Then use a long bolt and nut to securely attach to the base. I've included a before and after picture of this fix. It's very tight right now. However, a solid piece of metal for drilling.2. The swivel ball goes from loose to tight without providing a level of tightening that allows you to fine tune the position like other swivel balls I've used. That. For $18 now they are asking for a dual camera with a better phone holder, I would go for that instead if given the choice. I'm deducting one star for this modification, which I had to make because I didn't want to wobble.
