This page is a dated snapshot of four gaming mice tied to 2025 by the makers’ own material, and a guide to reading what they claim. It is not a ranking and not a top ten. The four dates are not equally firm, and each entry says how firm its date is. For how to choose a mouse by grip and size, see the mouse guide. For the full gear picture, see our gaming gear guide. The cover image is an illustration, not a photo of a specific model and not a Gimaxo test.

An earlier version of this page described nine mice in the first person, with prices, holiday sale figures and several claims we could not date. We kept only the mice whose 2025 launch we could confirm, and we removed the rest.

How we dated each launch

A product page that is online today does not prove a mouse came out in 2025. Only dated maker material counts here, and it comes in three grades:

• Dated announcement: a press release with its date, in which the maker announces the product.
• Calendar date: an entry in the maker’s release calendar. It shows a planned or listed release date. We could not confirm that the product shipped that day.
• Year only: a timeline that names a year and nothing more.

The four mice

Each entry separates three kinds of statement: the announced specifications, the comparisons the maker makes with its own earlier product, and the conditions in the footnotes. None of the figures below is a result measured by Gimaxo.

Razer DeathAdder V4 Pro. Dated announcement: 10 July 2025, in a Razer press release that announces the launch.

• Announced specifications: wireless ergonomic mouse; 56 g in black and 57 g in white; Focus Pro 45K Optical Sensor Gen-2 with up to 45,000 DPI, 900 IPS and 85 G; Optical Mouse Switches Gen-4 rated for 100 million clicks; up to 8000 Hz in wired and wireless modes.
• Marketing comparisons: “over 63% greater power efficiency and 37% lower latency than its predecessor”. The press release does not name the predecessor, so we cannot say what it is compared with.
• Conditions: “up to 150 hours” of battery at 1000 Hz polling.

Corsair SABRE v2 PRO Ultralight Wireless. Dated announcement: 18 September 2025, in a Corsair press release that also says the mouse is “immediately available”.

• Announced specifications: 36 g; 8,000 Hz in wired and wireless modes; CORSAIR MARKSMAN S sensor with 33,000 DPI, 99.7% resolution accuracy, 750 IPS and 50 G; switches rated for 100 million clicks.
• Marketing comparisons: “the lightest CORSAIR mouse ever”, a comparison with Corsair’s own range.
• Conditions: Corsair’s footnotes say reaching 8,000 Hz depends on CPU specifications, and that the “up to 70 hours” of battery life is measured at 2.4 GHz with a 1 kHz polling rate.

Pulsar X3 CrazyLight. Calendar date: Pulsar’s release calendar lists “X3 CrazyLight” for 20 October 2025. That is a calendar entry, not a dated announcement, and the entry does not name a size. The X3 CrazyLight Mini is a size variant sold on its own page, and the specifications below are for the Mini only.

• Announced specifications for the Mini size: 43 g, plus or minus 1 g, with dot skates; XS-1 sensor with 32,000 DPI, 750 IPS and 50 G; 100 million click lifespan.
• Conditions: Pulsar says up to 8K polling needs its 8K dongle, a recent Intel Core i5 or AMD Ryzen 5 or better, and a USB 3.0 or faster port.
• The calendar gives a date and no announcement text, so we cannot say what Pulsar claimed at launch or whether the Mini shipped on that date.

Endgame Gear OP1 8k v2. Year only: Endgame Gear’s company timeline places the launch of its v2 lineup in 2025 and gives no date. We keep the year and nothing more.

• Announced specifications: 49.5 g; PixArt PAW3950 sensor with 750 IPS and 50 G; wired USB 2.0; polling up to 8000 Hz; Kailh GX switches rated for 80 million actuations.
• Conditions: some features need firmware 1.02 or above, as the maker notes on its page.

What these four entries show

Read as lists, the four share a few things: all list 8,000 Hz or up to 8K polling, weights run from 36 g to 57 g, three give a DPI figure and all give a switch lifespan. The makers describe these as improvements. We have no independent measurement that shows what they change in play, so this page does not say whether they matter.

Reading the claims

• Compare the kind of figure. A weight is a specification. “37% lower latency than its predecessor” is a comparison with another product that you may not own.
• Read the footnote. Battery life, polling rate and wireless claims come with conditions that change the figure.
• Check the date. A launch date tells you the product has existed for a year or less. It does not tell you it is the best choice now.

What we could not verify

We found no source for the following, so this page does not state them: that any of these mice is better than another or than an older model, how any claim translates to play, prices (they change and sales distort them), and the launch dates of other mice named in earlier versions, which we could not place in 2025 from dated maker material. Nothing here was tested.
