good quality
Size: Width 16.5", Fully Adjustable Wall Mount, Style: Single
It is well built and does exactly as described. The only concern I have is the height adjustment. I have a 15 inch MacBook air and the wall mount is very touchy in the up position. My light weight MacBook has fallen to the down position on occasion. No damage but also not wanted action. But I would purchase again.

Just what I needed!!!
Size: Width 16.5", Fully Adjustable Desk Mount, Style: Single, Size: Width 16.5", Fully Adjustable Desk Mount, Style: Single
Just what I needed to improve my posture while working from home. Having a lower table was killing my back and neck.
Instructions pretty easy and clear for assembly, walks you through the steps to either use it for a laptop or for a monitor.
Really easy to adjust, excellent range of motion in all 3 axes, and 90% is metallic so the quality is superb, greatly recommended!

Sturdy, works well
Size: Width 16.5", Fully Adjustable Desk Mount, Style: Single
Been using this for awhile. I move it around a lot and it keeps up. My only complaint is it occasionally loosens so I have to find the tool and retighten it.
Mine also came with a piece broken, and I never got any sort of replacement part. That's a bit on me, but it's rather annoying when one of the laptop clips continuously falls off.

Absolutely fabulous products!
Size: Width 14", Adjustable Desk Mount, Style: Dual
The only downfall of this product is that there is no instant up/down adjustment on the arms. Otherwise this mount is outstanding. It is easy to put together, the only items you'll want that aren't in the box are a screwdriver and a wrench. It went up in just a couple of minutes, and it's sturdy and very well made. I like that I can put it flush to a wall because it does not need any room behind it. This is beyond amazing for the inexpensive cost. I would buy it again in a heartbeat. Also adding to the awesomeness is an array of additional arms and accessories for this you can find from Wali to make your setup perfect for you, all at great prices. I've got my office setup complete with three arms and two laptop trays and the whole thing cost less than a single arm I purchased from Amazon Basics. Handy thought regarding the laptop trays is that they're a nice size, and with the catch at the bottom, I've found I like to use it as a literature tray. I drop a book on there and it holds it at a nice angle to read from when transferring or referencing data. The trays do bounce some when typing, but much less than any other type of arm/tray system I've ever used. Highly recommended!

Not as complicated to put together as it seems, and quite sturdy
Size: Width 14", Adjustable Desk Mount, Style: Triple
When I first unpacked this stand, I was initially overwhelmed by the number of parts that were included in the package. I didn’t realize there were extra parts included to offer you two choices for how to mount the stand to your workstation. Once I got that sorted out, I relaxed a bit more and was able to assemble the unit single-handedly and mount two 22” monitors and a laptop to give myself more room on my desk. It was a bit challenging to move the arms to just the right angles and height, but I did get it after a few tries.
I used the re-positionable clamp instead of the desk- through grommet mount. It feels very sturdy, and I feel as long as I periodically check the tension and tightness of the bolts, it will hold up everything just fine.
I am not thrilled with the cable management clamps that attach to the round center pole, so I’ll probably end up looking for different clamps or even just velcro fasteners to loop around the post. The clamps that snap onto the arms themselves are fine and hold the Displayport and power cords in place well.
I thought about dinging this unit a star for the weird center post clamps and also because the black coating on part of the round post is flaking off, but really, I can work with those things/cover up the cosmetic issues.
I was super-impressed by the way the hardware was included in labeled, individual plastic compartments. The instructions were pretty good, too, although I would have liked the print to be a little larger - once you hit your forties, you reach for readers or have to get up close and squint to see small print…
Overall, I’m pleased with this unit.
