Introduction

North Bayou (北弧) is the budget champion of China’s monitor arm market, and the H100 gas spring single arm is their best-selling model. With 18,000+ JD reviews at ¥249 ($37), it’s the go-to entry level arm for budget-conscious desk setups — positioning itself as the gas-spring alternative to basic fixed stands.

The H100 supports monitors from 17-35 inches within a 6kg weight limit. It offers gas spring height adjustment, ±90° tilt, 360° rotation, and built-in cable management — feature parity with the Huanuo and Loctek arms at roughly 60% of the price. The critical question is: where did North Bayou cut corners to hit ¥249?

Design and Build Quality

The H100 uses a slightly thinner steel column (32mm diameter) than the Huanuo (38mm) and the Loctek D7D (42mm). The overall construction is adequate but clearly cost-optimized — the plastic cable management covers click on with less precision, and the adjustable tension mechanism uses a less refined ratchet system.

The C-clamp is smaller than premium alternatives, using a stamped steel construction with a 50mm max opening. The rubber pads are thinner and less cushioned. On the plus side, the arm mechanism is genuinely compact — the gas spring column is integrated seamlessly into the arm rather than bulging outward, giving it a cleaner profile than many competitors. The powder coat finish is uniform, though the internal metal shows slight roughness at the edges if you look closely.

“For ¥249 you can’t complain. Installed on a standard 25mm desk with a 24-inch monitor. Gas spring works smoothly, height adjustment is easy, and it’s held position for 3 months. It’s not premium but it does the job. I wouldn’t trust it with a heavy monitor though.” — JD.com user, Verified Purchase

Performance

The H100’s gas spring is surprisingly capable for monitors within its 6kg sweet spot. A 4.5kg 24-inch monitor required only minimal tension adjustment and held position perfectly from day one. The gas spring action is smooth with no “judder” or sticking points through the full height range — comparable to the Huanuo arm for monitors under 6kg.

However, at or near the 6kg limit, performance degrades notably. A 5.8kg 27-inch monitor initially held position but developed 1-2mm of sag per day over two weeks — requiring weekly retensioning. The tilt pivot felt less solid under heavier loads, with noticeable play. The arm reach of 50cm is generous for the price, but the pole connector section shows more lateral wobble (3-4mm) than premium arms at full extension with a 6kg load.

“Works perfectly with my 24-inch office monitor. Set it up in 20 minutes, cable management is tidy, and it freed up so much desk space. I tried it with my wife’s 27-inch 5.5kg monitor and it sagged a bit — moved her to a Huanuo arm instead.” — JD.com user, Verified Purchase

User Reviews by Theme

Theme 1: Performance/Quality

“Smooth as butter with my 24-inch monitor. The gas spring was well-tuned out of the box — no adjustment needed. For lightweight monitors this arm is excellent at any price, let alone ¥249.” — JD.com user 💡 Excellent performance with monitors under 5kg; most users in this segment are very satisfied.

Theme 2: Durability

“After 6 months, the VESA plate screws that hold the monitor to the plate had loosened slightly. Tightened them with Loctite and no issues since. The gas spring still performs like new.” — JD.com user 💡 VESA screw loosening is a minor but consistent issue; thread-locker solves it.

Theme 3: Value for Money

“¥249 for a gas spring monitor arm is incredible value. The same thing from Ergotron would cost 6x more. North Bayou arms are the Xiaomi of monitor stands — good enough for 90% of users.” — JD.com user 💡 Outstanding value for the gas spring category; acceptable for non-heavy users.

Theme 4: Common Complaints

“The 6kg limit is misleading. It handles 6kg initially but sags over time. I’d say the real comfortable limit is 5kg for long-term use. Also, the C-clamp doesn’t fit desks thicker than 50mm if you have a thick standing desk.” — JD.com user 💡 The 6kg weight limit is optimistic for long-term stability; 5kg is the practical ceiling.

Purchase Recommendations

⚠️ Budget Warning: Best for 24-inch monitors under 5kg. For 27-inch or heavier monitors, spend ¥140 more on the Huanuo (¥389/pair) for better long-term stability.

✅ Worth Buying: Excellent entry-level arm for home office setups with lightweight monitors. Best value gas spring arm under ¥300 ($44).

💰 Premium Pick: The Loctek D7D (¥479/$71) for users who expect zero sag and zero wobble with any monitor up to 9kg.

Pros & Cons

✅ Pros	❌ Cons
Lowest price gas spring arm at ¥249 ($37)	6kg limit too low for 27”+ long-term
Smooth gas spring action (<5kg monitors)	Sag develops over time near weight limit
Compact, clean profile	C-clamp max 50mm desk thickness
Quick 20-min installation	VESA screws loosen without thread-locker
Good for lightweight 24” setups	Pole wobble at full extension
Gas spring holds position well when properly tuned	Short 12-month warranty
50cm generous reach	Grommet mount not included

FAQ

Q1: What’s the real maximum monitor weight for the H100? For static long-term use, 5kg is the practical limit. The official 6kg rating will hold initially but may develop sag over weeks. A 4-5kg monitor gives the best experience.

Q2: How do I stop the VESA screws from loosening? Apply a drop of medium-strength thread-locker (Loctite Blue 243 is ideal) to each VESA screw before installation. This prevents vibration loosening while remaining removable with ordinary tools.

Q3: Does the H100 support 75×75mm VESA patterns? Yes, it supports both 75×75mm and 100×100mm VESA patterns. The VESA plate has two sets of mounting holes for both standards.

Q4: Can I upgrade the gas spring if it weakens? No, the gas spring is integrated into the arm assembly and is not user-replaceable. If the gas spring fails within the 12-month warranty period, North Bayou will replace the entire arm.

Q5: Is this arm suitable for a desk in a shared office? Yes, the H100’s gas spring adjustment is tool-free and quick — ideal for shared desks where different users have different height preferences. The arm profile is unobtrusive.

Verdict and Rating

The North Bayou Monitor Arm H100 delivers genuinely smooth gas spring performance at an entry-level price that’s hard to fault for lightweight monitors. The compromises become apparent at higher loads — the weight limit is realistic for 24-inch screens but optimistic for larger displays. If you’re equipping a budget home office with a standard 24-inch monitor, the H100 is a fantastic value. If you own a 27-inch or heavier screen, pay the premium for a Huanuo or Loctek arm.
