Pros & Cons
👍 Pros
- 57g weight class enables low-fatigue, high-velocity movement across extended gaming sessions without wrist strain accumulating over time.
- 8,000 DPI ceiling with on-the-fly switching covers the full range from precision tactical to high-sensitivity style without software interruption.
- Omron switches rated to 20M clicks provide a measurable durability floor that budget mouse switches don't offer.
- 100% PTFE feet deliver consistent, low-friction glide across both hard and soft mouse pads without the stickiness cheaper feet develop over time.
- Six programmable buttons cover macro, DPI, and side-button assignments without requiring a complex software layout.
👎 Cons
- Lenovo Vantage software for RGB and macro customization is Windows-only — macOS users get a functioning mouse with no software control layer.
- Small-medium symmetrical shell is optimized for claw and fingertip grip; palm grip users with larger hands will find the coverage insufficient for long sessions.
- 8,000 DPI is competitive but trails higher-end gaming mice in the 16,000–36,000 DPI tier, which matters for 4K+ display users running native high-resolution tracking.
- RGB customization is limited to the Legion logo — not per-zone or full-body lighting, which limits aesthetic flexibility compared to competitors at similar price points.
- Wired-only configuration with no wireless option, which constrains desk setups where cable management is a priority.
Frequently Asked Questions
What sensor does the M300s use, and how does 8,000 DPI translate to real-world tracking?
The M300s uses a tunable sensor adjustable from low sensitivity up to 8,000 DPI. In competitive play, most users lock between 400–1,600 DPI and adjust in-game sensitivity — the ceiling gives headroom for those who prefer high-sensitivity setups. On-the-fly DPI switching via the dedicated button means you can shift between precision and fast-swipe profiles without leaving the game.
Are the Omron microswitches in this mouse a standard replacement part if they fail?
Omron switches are an industry-standard component rated here for 20 million actuations — at 100 clicks per minute for 8 hours daily, that's roughly 27 years of theoretical use. Practical failure from normal gaming use before that threshold is unlikely. The switches are surface-mounted and technically replaceable by experienced hardware modders, but Lenovo doesn't publish a swap guide.
Is the M300s compatible with macOS, or is it primarily a Windows peripheral?
The mouse functions as a standard HID device on both Windows and macOS — cursor movement, clicks, and scroll wheel work without drivers. However, the Lenovo Vantage software for DPI customization, macro programming, and RGB control is Windows-only. macOS users get a functional mouse but lose software-layer customization.
What grip styles is the M300s optimized for?
Lenovo specifies claw and fingertip grip as the intended styles for the symmetrical small-medium form factor. Palm grip users — particularly those with larger hands — will find the low-profile shell doesn't fill the hand, which can cause fatigue over long sessions.
Does the 57g weight include the cable?
The 57g spec refers to the mouse body. The braided USB cable adds negligible drag in most setups, but users running heavy cable configurations may want a bungee to keep tension off the mouse during fast movements.
