The headline weight of Keychron G6 HE needs a version name beside it. Built-in and swappable power arrangements are different purchases, even when the shell looks familiar. This preorder is a useful reminder to compare the mouse that will arrive on your desk rather than the lightest number in the product family.
Quick Answer
The G6 HE brief lists a built-in battery version at 42g and a swappable version at 46g, each with a 3g tolerance. Choose the power arrangement and check hand fit before comparing mass. A R179 MARVO WS005 combo read on 9 October is a separate local budget reference, not a G6 HE quote.
🖐️ Start with the hand and the shell
Keychron gives dimensions of 123.7 by 63 by 41mm and positions the symmetrical shape around claw and palm use. Those measurements are more useful beside your current mouse than floating alone on a specification sheet. Look at where your palm touches, whether your fingers overhang and how comfortably you reach the side buttons. A light shell that makes you alter your grip constantly may be the wrong trade for a long evening.
Lift and reposition your existing mouse during a normal game before deciding which feature is missing. Is the problem mass, shape, cable drag or an unreliable button? Those are different reasons to upgrade. The range of gaming mice gives you a practical comparison point. Do not treat the lowest weight as a universal recommendation for every hand or every type of game.
🔋 Choose the battery arrangement deliberately
The built-in and swappable versions have different starting weights. Their published tolerances also mean the headline values are not a promise that every unit measures to the exact gram. Compare like with like when reading a review or discussing the mouse with another buyer. A test of one power arrangement does not establish the handling of the other.

A swappable design may appeal if your desk routine favours changing batteries, while built-in power keeps the arrangement simpler. Think about where spare parts will live, what comes in the box and how charging fits into an ordinary week. Ask for the exact version name on the quote. That small step prevents a buyer from choosing based on the 42g headline and receiving a configuration they meant to avoid.
🎯 Separate fast reporting from useful control
The family advertises polling up to 8000Hz. Check the required connection mode, receiver and software before assuming the headline setting is active. Then test a sensible reporting rate in the game you actually play. Faster input reporting is not a replacement for stable frame delivery, a comfortable surface or a grip that allows controlled movement. Keep your ordinary sensitivity consistent during the first comparison so the result means something.
The G6 HE is a specialised mouse purchase, while the R179 MARVO listing includes a membrane keyboard and mouse for basic input. Complete input combos belong in a different budget calculation. For the new Keychron model, request the local version, accessories and support terms together. Buy when the shape and battery choice solve a clear problem in your setup; wait if the current mouse already fits well and the only attraction is a number you have not connected to a real need.
Frequently Asked Questions
Are both versions 42g?
No. The brief lists 42g for built-in power and 46g for the swappable version, with a 3g tolerance on each.
What is the shape size?
The published dimensions are 123.7 by 63 by 41mm. Compare those dimensions with a mouse that already fits your hand.
Which grip styles are described?
Keychron positions the symmetrical shape for claw and palm grips. Your hand size and preferred contact points still matter.
Does a lighter mouse raise frame rates?
No. Lower mass can change handling, but it does not increase the PC graphics performance.
Is the headline rate universal?
Check the exact connection mode and receiver requirements. The family is advertised with polling up to 8000Hz.
Is there a South African launch price here?
Request the exact local G6 HE quote separately. The R179 MARVO combo read on 9 October is a different product.
