## What reviewers say

**Ergotron LX Pro Desk Monitor Arm (Matte Black)** — 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.)

**HUANUO Single Monitor Arm Mount HNSS6** — One whitelisted tester, PCWorld, reviewed the exact HUANUO HNSS6 hands-on, naming it the best single-monitor arm under $50. They praise its overall build quality, easy install (just three screws), and gas-spring hold, verified with a 12-pound, 32-inch panel in testing. Downsides: finicky plastic cable-management covers that won't hold many wires, and it is not as easy to set up/adjust or as sturdy as the pricier Ergotron LX and Monoprice arms. (1 sourced review.)
