This product was easy to assemble and install and came with all parts. The product itself is very sturdy, looks good with a nice industrial aesthetic BUT - there is ZERO stability side to side (lengthwise) as the plates which attach to the wood are too small. I have them set closer than the picture so it is not an issue of being too far apart. If anyone else had this problem AND FIGURED OUT A FIX FOR IT - please share!!

Fairly stable. Good value for the price

Great set of stands. You have to tighten them pretty snugly to minimize wobble. Given they are metal they’ll have a little bit more give than solid wood. Even so, a tall desk I built with them remains stable and level.

Perfect

Exactly what I ordered, took just a few minutes to assemble and mount the legs. Love that the bottoms can be manipulated to give a balanced stance.
