Full research notes and sources

Tracking and sensor

The Focus X 18K sensor is a mid-tier part: 18,000 DPI, 350 IPS and 35 G, with a manufacturer-claimed 99.4% resolution accuracy. PCMag and Windows Central found tracking stable across surfaces. The sensor is not the flagship Focus Pro, and its 350 IPS/35 G ceiling sits below top Razer mice. HyperSpeed 2.4 GHz mode runs at 1,000 Hz; Bluetooth mode drops to 125 Hz but extends battery life.

Battery life

TechRadar saw battery fall to 70% after two days of mixed use, which casts doubt on the 105-hour figure. Owners also report rapid drain in some cases. How-To Geek calls battery life “nice”.

Comfort and portability

The shape is a high-rear-hump right-handed ergonomic with a thumb rest, comfortable for small hands and cramped for large ones. How-To Geek found it uncomfortable for larger hands. Several reviewers note it is not meaningfully smaller or lighter than standard gaming mice, so the travel framing is disputed. PC Gamer measured 77 g against the 76 g manufacturer figure.

Software and customization

Razer Synapse 4 handles remapping, macros, DPI stages, HyperShift and on-board profiles, but only one profile is stored on the mouse and saving it can be finicky. Lighting is limited to a single logo zone. The AI Prompt Master button behind the thumb is prone to accidental presses but is remappable. Gen-3 optical switches are rated for 90 million clicks and feel crisp. Firmware updates are handled through Synapse.

Reliability and warranty

No teardown or repairability data was found. The battery is internal and not user-replaceable, and no spare skates are included. Warranty is up to 2 years per the manufacturer, 2 years parts and labor per PCMag, and 2-year standard per Windows Central. One owner reported 8 of 8 units in their team developing issues within 6 months; this is a single unverified anecdote, not a defect rate.

Is it worth it?

Reviews list the mouse at $89.99 (PCMag, TechRadar, How-To Geek, Windows Central, PC Gamer, 2026), with TechRadar also listing £89.99 and AU$169.95 and PC Gamer listing £90 and AU$170. PCMag calls it excellent value and an Editors’ Choice for travel mice; TechRadar and Windows Central find it well-priced but note rivals at similar prices; How-To Geek and PC Gamer say it is too expensive for what it offers. Windows Central points to the DeathAdder V3 HyperSpeed for better performance at a similar price, minus Bluetooth and some buttons. Based on the reviewed opinions: at or below $70 it is strong value if the compact ergonomic shape is wanted; from $71 to $90 it is fair to good value, with the multi-mode connectivity and 10 inputs justifying the price only if those features are used; above $90 it is weak value unless the compact Basilisk shape and tri-mode connectivity are specifically required. One review notes a lower retailer-specific price but does not publish the figure. No discount data beyond the reviewed retail figures was found. There are no consumables or subscription; the internal battery is rechargeable and not user-replaceable, and no spare skates are included or priced in the sources read.
