The item was quite sturdy and looked like it would work but when we received the product, we realized our exam room setup would not allow us to use the product so we returned it.

...i have been buying mounts over the years; setting up, moving and replacing many studio/offices. and for the moment, this ergotron LX-Series is my new favorite in terms of quality, build, articulation, adjustibility and overall function.These are not small. and these are not cheap. but if you want solid quality, they certainly fit the bill.... a few suggestions / lessons learned .(1) always use best cables and keep in mind you'll need no less than say a 3meter lengths. that's 1.5meter to lace up the arm to your desk, then additional length to reach the port replicator or computer. (i've found 3meters are most used, 5 meters are my favorite).(2) hardwood desktops or millwork is a must. the amount of force transmitted onto the deskclamp is basic phyics.

And at the risk of stating the obvious, do not expect pressboard or light-weight consoles to hold.(3) never can have enough pole rings (PN#97-844). ergotron is great at supplying necessary hardware in their kits, with exception of the pole rings. ... for some reason they seem to skimp and only ever send one ring with the monitor LX-sit-stand kit. and if you want to mount this keyboard to the desktop kit, it is perfect but you'll need an additional ring.All told, the ergotron LX series sit-stand products are top-shelf and premium...my recommendation, if you've the time, would be to contact BHPhoto tech team, who i am sure would have lot's of great advice and options beyond my little write-up.keep well, everyone ! and stay healthy.

This arm does the trick of supporting my keyboard and mouse so that I don't need a table or counter. It adjusts to sitting or standing heights. It is VERY heavy. It MUST be mounted in a stud.
