CotytechDual Apple Desk Mount Spring Arm Clamp Base - Silver (DM-GS2A-C)

Takes a while to fully assemble but it works and looks great. The hardest part was taking the stand out of the monitor. I found a thicker piece of plastic than the one they have worked best. Otherwise works great. I’m able to use one of my monitors in portrait and the other in landscape.

Overall works well enough, currently holding a single 2010 iMac.2nd arm not currently attached/in use.Pros:- Fairly straightforward to setup.- VESA mount fits well.- Does what it’s supposed to do.Cons:- Plastic retainers are cheap, one broke in shipping, another during setup. The plastic retainers in the cable channel are also too stiff and sharp, they will mark up or slice your cables if you’re not extra careful.- mounting flexes quite a bit. I mounted directly to the pole itself as I’m only using one arm atm. It looks like it SHOULD hold, but I would be shocked if it would actually hold two iMacs. Maybe it’s by design, but the pole flexes a good inch or so with my iMac mounted.To be fair, this was an open-Box purchase; so I saved quite a bit over the full price.I probably wouldn’t be as happy if I didn’t get such a good deal.That said, there don’t seem to be many options for VESA arms that will attach directly to an iMac, or do so without being completely fugly.Despite the cheap plastic and the mount flexing, it seems like a decent product.It’s not perfect, but nothing ever really is.It works; and ultimately, that’s all that matters.

I use these with 2 Apple Thunderbolt displays and have no complaints. Easy to assemble and get the monitors up and on them. The setup is very sturdy and strong. My clamp is a little wobbly but that has nothing to do with the clamp itself but my MDF core desk. A solid wood top would eliminate that. You also have to understand that's over 40lbs these are supporting. The best part is I didn't;t need the Apple VESA adapter. The arms have the 2 bolts you need (That the Apple VESA mounts would use to attach) and just connect directly to the end of the arm. Easy to adjust and sty where I set them. These are well worth the money.

I was looking for a double arm set for my 2 Apple Thunderbolt monitors (yes old but still very good).And they are very heavy (27lbs each), so no just any arms would work.The assembly it not super straight forward, but simple enough with the little guides that are included.The quality of the materials is quite impressive, and the whole thing is very sturdy.I'm still playing around with the setup, which is easy enough to do.Once I'm happy with how everything is, I can easily tighten every articulation to "freeze" the whole set in place.One thing that was not 100% clear in the description (though the seller explained in a question I posted): the monitors are rotatable, so i can easily see 100 lines of code at once!

I am loving this mount, and in my setup it works perfectly, allowing me to arrange two Thunderbolt Displays in a portrait configuration. It feels rock steady and handles the very heavy displays quite nicely.That said, the pictures and descriptions of the item insinuate that the item comes with both a clamp mount and a grommet mount. That is not the case. I was able to make the clamp work on my desk, but my preference would have been to use a grommet base, which you much purchase separately.

Love it! Looks great and didn't take too much time to install. Very well made, sturdy after the installation, and doesn't look cheap.Monitors are easy to move, have just the right amount of friction, and stay exactly where you put them when you let go. Infinite degrees of freedom.Exactly what I was looking for!

This is a great design, just too heavy for a standing desk. Changed to single and live it!

Works very well but very heavy. Setting it up is definitely a two person job once the monitors are attached. My shipment arrived with a missing part, and as soon as I contacted the shipper about it, they immediately sent out the missing part to me.
