if its not tight enough you can tighten it on some certain bolts on the side that make it so the monitor cannot fall down. By the way i chose to mount using the clamp and it still works perfect
There is some rotational looseness in the monitor connection point of the stand. If you move the monitors around often it takes longer to get the monitor exactly where you want them. I set my monitors and don't move them, so after setup everything is good. If you have monitors less than 32", (mine are 2, 28"), the smaller they are you will want room behind the stand or the monitors will have to move out toward the user. Not a problem for me but something to keep in mind.
They were easy to assemble, but really hard to dial in, especially with two 32" inch monitors that are nearing the upper limits of the supported weight. If you don't have a third hand helping out, you'll need to get creative in how you support the monitors while finding the pitch you want. If your monitor is on the heavier side you'll have to tighten it so much that you won't be able to change the angle of the pitch up or down without loosening it first - queue the third hand, shoe box, or your wildly dexterous, strong, and well trained cat/small dog. Otherwise the height, depth, and rotation - at least the minor rotation for leveling, work well and as you'd expect.
I had to return the item because it took up too much of my desk. But that is no knock on the product. It was solid and worked well, I just chose another avenue with a wall mounted version instead. Just know it takes up a lot of your desk space.
So, you've got two monitors - either because you've got two PCs or you've got one PC that's driving two displays. You could just keep the monitors on their stands and give up a chunk of desktop real estate to the bases, or you could get this! Clamps onto the edge of your desk or into a porthole if your desk is drilled for one - it comes with hardware to do both!The mounting bracket includes sockets to hold both of the Allen wrenches (provided!) that you'll need to both set up and adjust the arms afterword. Cable guides on the back of the base and the arms helps to keep everything neat and tidy. Base is adjustable, so you can move the arms up or down to suit your layout. Clamp is solid with a broad head to provide stability and distribute the clamping force. It comes with an assortment of screws, standoffs and requisite parts to get almost any VESA-compliant device attached easily. Speaking of which, the VESA clamp is spring-locked and easy to unlatch if you need to unmount a monitor for maintenance or replacement.Solid device, good price, works a treat and looks good doing it. Highly Recommended.
