Build Quality
The MU6016B uses steel construction throughout both arms, rated to hold 4.4 to 22 lbs per arm - a range wide enough to cover everything from a lightweight 13-inch secondary display up to a dense 32-inch 4K panel. MOUNTUP does not publish the exact gauge of steel used, which is a transparency gap worth noting. The C-clamp hardware accommodates desks from 0.39 to 2.76 inches thick, and the grommet mount handles holes from 0.39 to 2.36 inches wide. Both installation types are included in the box. The base pole is shared between both arms, which keeps the footprint compact but means any wobble in the pole base affects both screens simultaneously - a physics reality no dual-arm mount at this price avoids.
Comfort and Ergonomics
The 26.6-inch total height adjustment range is the standout ergonomic specification here. Most budget dual arms offer 15 to 18 inches of vertical range; 26.6 inches means a 5-foot-2 user and a 6-foot-3 user can share the same desk setup without either person accepting a compromised eye-line. Tilt adjusts from +70 degrees (looking down at the screen from above) to -45 degrees (tilting the screen face upward), which covers every reasonable seated and standing viewing angle. Each arm swivels ±90 degrees horizontally, so you can angle both screens toward a corner position or pull one screen directly in front of you without rerouting cables. The 360-degree rotation per monitor head enables true portrait mode, useful for coders and editors running one vertical monitor alongside one landscape screen.
Adjustability
Gas spring resistance - not friction knobs - holds screen position across the full 18.1-inch arm reach. This matters practically: when you push a screen up or pull it forward, it stays where you leave it without drifting. Competitors at the $100 to $120 price point frequently rely on friction-based tension screws that loosen over 12 to 18 months of daily repositioning. MOUNTUP does not publish gas spring pressure ratings in Newtons, so calibration data for extremely light monitors (under 5 lbs) is unavailable - buyers running lightweight 13-inch screens should verify compatibility directly with MOUNTUP at cs@mountup.com before purchasing. VESA compatibility covers 75x75mm and 100x100mm patterns, the two most common standards across ASUS, Acer, Samsung, Dell, and LG consumer monitors.
Assembly
MOUNTUP ships both C-clamp and grommet hardware in the same box, so you do not need to select a mounting type at checkout. Standard tool requirements are a Phillips screwdriver and the included hex key. The arm attaches to the central pole with a collar clamp, and height on the pole is adjustable before final tightening. No assembly time data from verified third-party sources is available, but single-arm gas spring mounts of similar construction typically take 20 to 35 minutes for a first-time installer. Dual-arm setups add complexity because both arms must be balanced against each other on the pole - plan for 45 to 60 minutes if this is your first monitor arm.
Value for Money
The $139.99 sale price (down from $159.99 regular) positions the MU6016B between budget dual arms around $100 and premium options from Ergotron (LX Dual at $299) and Fully (Jarvis Dual at $249). The Monoprice HD dual arm undercuts it by $20 to $35 with a 1-year warranty versus MOUNTUP's 3-year coverage. That 2-year warranty difference represents real financial protection on a product containing gas spring mechanisms that can degrade - if a gas spring fails at month 14, the Monoprice warranty has already expired while the MU6016B is still covered. Buyers who adjust monitor position infrequently and primarily want monitors off the desk surface will find adequate value in the Monoprice. Buyers who reposition screens multiple times daily get meaningful utility from the smoother gas spring action and longer coverage window the MU6016B provides.
