Claude vs ChatGPT: Cheap vs premium monitor arm: honest comparison. Join the debate.: North Bayou F100A

For most people, a mid-range arm in the £30–60 range is the sweet spot — something like the Ergotron LX or the Amazon Basics monitor arm. The Ergotron LX holds position reliably over years, handles monitors up to 34 inches, and the build quality justifies the ~£150 price if you're at a desk all day. The cheap £15–25 arms on Amazon tend to droop over time and the gas spring loses tension within months. The honest answer: if your monitor is under 27 inches and you're not adjusting it daily, a mid-range arm like the Huanuo Dual or North Bayou single arm (~£35–45) will do the job. Spend more if you have a heavy ultrawide or want it to stay exactly where you put it for years.

Fair challenge. The clamp mechanism is where mid-range arms tend to show their weakness — cheaper clamps use thinner steel and narrower contact surfaces, which means they can loosen or bite into desk edges over time, especially on laminate desks. For a 5kg monitor, the North Bayou F100A (~£35) handles this reasonably well — its clamp spreads load across a wider contact area than most budget options. But the Ergotron LX is the honest answer for long-term stability: its clamp is machined aluminium, it won't creep, and the gas spring holds 5kg without sagging after a year of daily adjustment. If desk damage or long-term drift matters to you, the Ergotron LX is worth the premium.

The North Bayou F100A clamps reliably to desks up to around 60mm thick. The Ergotron LX handles up to 64mm — a small difference, but its clamp maintains consistent clamping pressure across that range without the micro-creep you see in cheaper mechanisms. For a 5kg monitor on a standard desk, my final recommendation is the Ergotron LX. It's the only arm in this conversation that genuinely solves all three variables — it holds 5kg without gas spring sag, the aluminium clamp won't damage or loosen on a standard laminate edge, and it stays exactly where you put it after two years of daily use. The North Bayou is fine for occasional adjusters on lighter monitors. For a heavy monitor used seriously, the Ergotron LX is the right buy.
