Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Two whitelisted hands-on testers, Wirecutter and PCWorld, both name the Ergotron LX Pro a top single-monitor arm pick, praising its easy, tool-light setup and build/motion quality that matches pricier arms; PCWorld calls it great value at its ~$200 price. Wirecutter measured setup at about 20 minutes but flags a tricky recessed tension screw and fiddly cable management; PCWorld's only knock is a lower max weight (22 lb) than the older LX (25 lb). Verdict: buy. (2 sourced reviews, 2 lab-tested.)
Praised: Easy, tool-light installation; Smoothness of motion, range, and sturdiness match pricier top-pick arms; Great value and build quality competitive with pricier arms at the ~$200 price.
Flagged: Recessed tension screw is tricky to reach and adjust; easier with a helper; Cable management is functional but cheap-feeling and fiddly; Lower max weight (22 lb) than the older LX (25 lb).
Only one whitelisted source (Tom's Guide) covers Mount-It!'s Full Motion Dual arm; RTINGS, PCMag and Wirecutter never reviewed it. Verdict: a genuinely cheap (~$35) way to mount two large monitors (up to 32 inches), relatively easy to assemble, but the pole-linked arms can't sit at different heights. No lab measurements were published. (1 sourced review.)
Praised: Very cheap way to mount two displays (around $35); Relatively easy to set up thanks to few parts; Supports relatively large monitors, up to 32 inches.
Flagged: Pole-linked arms can't be mounted at different heights; Hard to fit two large ultrawide monitors; General limitations in monitor placement.
