Mostly painless install, packaging was subpar but everything works well. Holds a 27" monitor and a 24" monitor very well. Adjustable angles and hinges allowing for customization for your needs. Seems to be very sturdy and hasn't dropped since making sure everything is tight. Overall, worth it compared to more expensive options.
