WALI Dual Monitor Wall Mount for 17-38 Inch, Ultrawide Monitor Arm for 2 Monitors, Swivel Tilt Computer Wall Mount with Mounting Holes 75x75/100x100 mm, Holds Up to 10 kg per Arm (012ARM-38), Black

This item works well. All the parts were in the box, and the instructions were easy to follow. I had fun installing it.

Almost a brilliant product, but falls short in a couple of annoying ways. Not sure why people are complaining about the wall mounting; simple answer is just to replace the fixings for whatever is suitable for the substrate it's going to.The swivel mounting plates are incredibly stiff. True, you don't want the screens moving on their own, but trying to straighten them out was silly and need pliers and brute force.Biggest issue is the length of the arms. I have two 22inch screens, the listing is for 17-32inch screens, but with the mounts at their closest, there is still an 80mm gap between the screens. Fortunately I can cut the centre arms down and re-drill the through holes, but if you're not comfortable doing that - avoid this product.
