Pros
- Constant Force lift mechanism holds position smoothly across its full range without drift, which matters more as monitor weight climbs
- Cast aluminum construction and a 10-year warranty signal genuine longevity rather than marketing fluff
- Supports heavier displays than most budget arms, comfortably handling typical 34-inch ultrawides within its rated capacity
- Wide range of motion with integrated cable management keeps an ultrawide setup clean and adjustable
Cons
- Priced well above generic gas-spring arms, and you're paying for the brand and warranty as much as the hardware
- Very light monitors can be hard to dial in because the spring tension favors heavier loads
- Standard model tops out before the heaviest curved ultrawides — those need the LX HD variant
