Summary
A 54 g ultralight wireless esports mouse built around a 35,000 DPI sensor, optical switches and 8000 Hz wireless polling through the dongle in the box. Check how you plan to connect it before you buy: the 8000 Hz rate is wireless-only, wired mode tops out at 1000 Hz, and there is no Bluetooth.
Strengths
- The 54 g body cuts hand fatigue over long sessions.
- Large 100% PTFE feet glide smoothly on most surfaces.
- The Focus Pro 35K sensor tracks accurately, including on glass.
- Optical Gen-3 switches fire in 0.2 ms with no debounce delay.
- The HyperPolling dongle is included rather than sold separately.
- The symmetrical shape suits claw and fingertip grips.
Weaknesses
- Wired mode is capped at 1000 Hz, so the 8000 Hz rate needs the dongle.
- Battery drops from 95 hours at 1000 Hz to about 17 hours at 8000 Hz.
- No Bluetooth and no multi-device pairing.
- The braided cable is stiff, which makes wired play while charging awkward.
- No free-scrolling mode or left/right tilt on the wheel.
- Owners report wheel wobble, sensor stutter and battery failures.

Full research notes and sources
Battery life and polling rate
Razer rates the mouse at up to 95 hours at 1000 Hz, but that headline assumes the low polling rate. At 8000 Hz, Razer’s own figure cited by PCMag is about 17 hours, so plan on charging more often if you run the competitive setting. The 8000 Hz rate also needs the bundled HyperPolling dongle and is wireless-only; PCMag and How-To Geek both put wired mode at 1000 Hz. The dongle is large and can block an adjacent USB port, as The Verge noted. Charging is over USB-C, and no dock is included.
Sensor, switches and glide
The Focus Pro 35K Optical Sensor Gen-2 is the core of the mouse: 35,000 DPI, 750 IPS, 70 G acceleration and 99.8% resolution accuracy. Razer’s Optical Mouse Switches Gen-3 are rated for 90 million clicks at 0.2 ms actuation and are marketed as immune to double-click faults. The body uses a smooth-touch finish, and grip tape is in the box.
What owners report
Others report side-to-side play and crunching in the scroll wheel after months of use. At least one owner says the mouse stopped holding charge inside warranty and calls the RMA process difficult, and some report the shell creaks when gripped. Nobody has published a failure rate, so treat these as known annoyances rather than measured defects. Razer has shipped firmware updates; RTINGS retested in April 2026 on firmware 1.14.0.0 and measured marginally worse click latency.
Repairs, parts and running costs
The battery is internal and not user-replaceable, and no teardown or repairability score was found. Razer sells some parts, such as mouse feet, through its support site. Razer lists Razer Mice at 2 years limited warranty, and RazerCare extended plans are optional. Running costs are limited to electricity for charging: there is no subscription and no proprietary consumable, and the HyperPolling dongle is included.
Is it worth it?
At $130 or less the mouse is good value for a competitive player: top-tier sensor, 8000 Hz wireless polling with the dongle included, and a 54 g shell. RazerStore lists $129.99 (2026-10), and Windows Central reported $129.99 at Best Buy in December 2025. Near the $159.99 launch price the case is weaker given the community-reported sensor and wheel concerns and the missing Bluetooth, though the 2-year warranty helps. If you want the same shape for less, the Viper V3 Pro SE ships with a 1000 Hz dongle; 8000 Hz needs a separate HyperPolling dongle.
Which model this is
This page covers the Razer Viper V3 Pro (model RZ01-0512), the ultralight symmetrical wireless mouse. The black US variant is ASIN B0CVRGCGWJ. Do not confuse it with the Viper V3 Pro SE, which ships with a 1000 Hz dongle, or the Viper V3 HyperSpeed, a heavier 82 g model with a different sensor. Razer has since moved the flagship slot to the Viper V4 Pro.
