Product 2: MonsGeek M1 V5 HE
4.7

The reviews repeatedly describe the keyboard as premium, heavy, aluminum, solid, and well built, with only minor concerns about a loose-feeling shell or rapid-disassembly sensitivity in some units.

cable quality
Product 1: GravaStar Mercury V75 Pro
2.2

The included cable is a weak point in the one review that discusses it, because it is a plain rubber USB cable rather than a braided cable.

Product 2: MonsGeek M1 V5 HE
3.6

materials quality
Product 1: GravaStar Mercury V75 Pro
4.5

Materials quality is high, with repeated references to aluminum alloy, metal, full aluminum case construction, and sturdy high-quality materials.

Product 2: MonsGeek M1 V5 HE
4.7

Materials quality is a standout strength, with repeated evidence for aluminum construction, premium weight, PBT keycaps, and high-quality materials.

media controls
Product 1: GravaStar Mercury V75 Pro
4.1

Media controls are present through a volume knob or lever, including mute behavior, though it is not always a traditional rolling knob.

Product 2: MonsGeek M1 V5 HE

polling rate
Product 1: GravaStar Mercury V75 Pro
4.4

Polling rate is a high-spec strength, with multiple reviews citing or testing 8,000Hz polling, though one reviewer considered it more marketing than noticeable.

Product 2: MonsGeek M1 V5 HE
4.6

Polling-rate support is a strong gaming point in TMR/HE reviews, with multiple mentions of 8K wired/wireless polling and lower Bluetooth polling on VIA models.

portability
Product 1: GravaStar Mercury V75 Pro
2.6

Portability is a weakness because the board is heavy, wired-only, and visually or physically bulky despite its 75% layout.

Product 2: MonsGeek M1 V5 HE
2.5

4.4

Volume control is a common knob use case, with several reviews noting default volume control or reprogrammable knob behavior.

wireless performance
Product 1: GravaStar Mercury V75 Pro
1.4

Wireless performance is a clear weakness because the keyboard has no Bluetooth or 2.4GHz wireless mode and is wired-only.

Product 2: MonsGeek M1 V5 HE
4.4

Wireless performance is mostly positive, with stable dongle/Bluetooth use, no lag, low-latency claims, and efficient wireless behavior; Bluetooth wake or minor connection issues appear in some reviews.
