Five years and we had Zero RMA's. No loose joints. No sagging or tilting monitors.After trying a number of other models, this is hands-down the only monitor stand I will ever buy for my office.___________________________________PRO'S:_____________________________An AMAZING and unique feature that no one discusses: the foot on this stand is FLAT.This stand doesn't take up ANY desk space because you can still use your entire desk surface!Put your laptop on it, put a cold glass dripping with condensation on it, put your keyboard on it, pile papers all over. You won't even notice it's there.Now I will tell you how to avoid the two potential hazards:1) Tipping overEasy fix! Just don't bend the arms so far forward!* Most people will pull both arms towards themselves if they want make the monitors touch. Don't do it that way. Slide the monitors left and right along the arms to bring them closer together.* You only need to pull the arms forward to adjust the V shape angle. Slide the monitors and you won't need to pull them far enough to tip it over.* When you want an extremely acute V angle: only bring one arm forward, leave the other arm far back, and rotate the foot until your face is in the middle of the V.2) Parts do not fit/poor build quality* Unlike all the cheap stands out there, the entire thing is 100% well-machined steel. The only plastic parts are the clips.The parts fit like a glove.* FOLLOW THE INSTRUCTIONS!Go step by step and don't skip. Don't just read the parts about where to put the screws. You will need the included allen wrench to lock in the tilt, monitor distance, arms, etc. There are many places to tighten. Get those screws really tight!Set it up right and nothing will move ever again.* Take your time when screwing the post into the base. Line up the threads before screwing it in. Otherwise you'll torque it at an angle and it'll never go in.* Use the plastic ring to position the arm height *before* you put the monitor arms on (it's in the instructions!)Really tighten the ring, but don't rely on it to hold the monitors up. It's only there to help you screw the monitor arms on at the right height. Those two screws on the back of the monitor arm's clamp are what hold the arm in place. Get those screws really tight!* I usually tighten the four monitor tilt screws before I even test putting a monitor on them. Don't rely on them being tight enough right out of the box.Get those screws really REALLY tight when you are happy with the tilt.* There are rubber pads. Use them if you're worried about scratches or your coffee cup's heat damaging your desk's surface.* HERE IS THE EASY WAY TO GET EVERYTHING POSITIONED HOW YOU LIKE ITThe back of your monitor has four VESA mount screw holes. The stand's VESA bracket has two cut-outs and two screw holes. The cut-outs point UP.* On the back of your monitor: put screws in the top two VESA screw holes. The two screws will let the monitor hang from the cut-outs.* Hang the monitors on the cut-outs, sit in your chair, consider my (1) suggestions above, remove the monitors, make adjustments, repeat until perfect.___________________________________CON'S:_____________________________My only complaint: the pole's plastic clips for wire management are small. Two thick VGA video cables plus two thick power cables can be too much. When that happens I replace the two clips with black velcro strips or black zip ties.Doing the job right can be time consuming, but do it right and you'll never worry about it again.
