The Best Ultra-Light Gaming Mice
Five gaming mice ranked on weight and button count, where the ROG Harpe II Ace has the lightest weight; the M725 is the cheapest route in.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated
Ultra-light mice under 55g reduce fatigue in fast games. Every pick weighs 55g or less, ordered from the lightest.
Rankings weigh weight, programmable buttons and max DPI as the makers state them; if a maker skips programmable buttons, the guide says so rather than guess, since we have not benched them.

Our Picks
Lightest Mouse1 of 5
ASUS ROG Harpe II Ace
The ROG Harpe II Ace is built around track-on-glass sensing.
Best for
- Players who lift the mouse often at low sensitivity.
Skip if
- Price-first buyers should look at the M725, which cost less when we checked.
Why we like it
On the spec sheet, it weighs 48g and offers a 42,000 max DPI. Its 48g weight is the lightest here; the M725 comes next at 49g. It is the only pick here with a wireless connection; the Model O 2 Mini has a wired connection instead.
The ROG Harpe II Ace's dongle works best on a front USB port or an extender near the mouse. Polling above 1,000Hz shortens battery life and needs a CPU with headroom. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the DeathAdder V3 HyperSpeed and the rest. The maker doesn't give its button count; if that figure matters, the DeathAdder V3 HyperSpeed offers 8.

Lowest Price Here2 of 5
Redragon M725 Wireless Gaming Mouse
Redragon's M725 is a 49g symmetrical tri-mode mouse with a honeycomb shell.
Best for
- Buyers who would rather put the savings elsewhere than into the Pulsefire Haste 2.
Skip if
- Worth skipping when weight of 49g, behind the ROG Harpe II Ace (48g) is a problem.
Why we like it
It stores five configuration modes onboard. On weight it ties with the Model O 2 Mini at 49g. It also offers tri-mode connection at a budget price.
Keep the M725 on its dongle for games; Bluetooth is for a laptop. Another plus: light 49g body. The nearest alternative on button count is the DeathAdder V3 HyperSpeed at 8, against 5 here.
No other pick here cost less at our last price check, and the Pulsefire Haste 2 was closest. If you want a confirmed polling rate, look to the ROG Harpe II Ace instead: it offers 8,000Hz, while this one gives no figure.

Glorious Model O 2 Mini Wired Gaming Mouse
Glorious's Model O 2 Mini is a 49g symmetrical wired mouse with a 26K sensor.
Best for
- Buyers who want symmetrical shape Glorious lists for palm, claw and fingertip grips.
Skip if
- If budget leads, the M725 was cheaper at our last price check.
Why we like it
Glorious lists it for palm, claw and fingertip grips. It weighs 49g in a compact symmetrical shape for palm, claw or fingertip grips. The wired design avoids charging.
Glorious rates its switches for 80 million clicks, and the sensor includes Motion Sync. Six programmable buttons cover the usual binds without adding weight. It matches the M725 on weight (49g).
Like the Pulsefire Haste 2, it has a wired connection, while the ROG Harpe II Ace uses a wireless connection. Its price falls between the Pulsefire Haste 2 and the DeathAdder V3 HyperSpeed, based on our last check. Buyers who need a confirmed button count should compare it with the DeathAdder V3 HyperSpeed, which offers 8.

- 49g
- Max DPI
- 26,000
- Connection
- Wired
- Shape
- Symmetrical, compact
Pros

Strong Alternative4 of 5
HyperX Pulsefire Haste 2 Wired Gaming Mouse
HyperX's wired Pulsefire Haste 2 weighs 53g and reaches 8000Hz polling.
Best for
- Buyers who want four pieces of included grip tape.
Skip if
- Price-first buyers should look at the M725, which cost less when we checked.
Why we like it
Grip tape is included. It weighs 53g with a solid shell rather than holes, and the HyperX 26K sensor tracks up to 26,000 DPI. The wired cable keeps it simple.
Its paracord-style HyperFlex 2 cable reduces drag, and it polls at up to 8,000Hz, reporting every 0.125ms. Its 53g weight ranks fourth of 5 here, behind the ROG Harpe II Ace (48g) and ahead of the DeathAdder V3 HyperSpeed (55g). Like the Model O 2 Mini, it has a wired connection, while the ROG Harpe II Ace uses a wireless connection.
Polling above 1,000Hz shortens battery life and needs a CPU with headroom. On price it sat second of 5, between the cheaper M725 and the pricier Model O 2 Mini, at the time of writing.

It also offers Gen-3 optical switches rated for a 90-million-click lifecycle and USB-C charging. The DeathAdder V3 HyperSpeed's dongle works best on a front USB port or an extender near the mouse. It was priced above the Model O 2 Mini and below the ROG Harpe II Ace at the time of writing.
