Its listed 135 g (0.30 lbs) with AA battery weight and 115 mm (4.53 in) × 74 mm (2.91 in) × 45 mm (1.78 in) dimensions make the Palm, Claw guidance central to the buying decision.

✋ Shape & Grip Guide — Is This Mouse Right for Your Hand?

ShapeRight-handed
Size115 mm (4.53 in) × 74 mm (2.91 in) × 45 mm (1.78 in)
Weight Feel135 g (0.30 lbs) with AA battery (heavier)
Best GripsPalm, Claw

Logitech M720 Triathlon measures 115 mm (4.53 in) × 74 mm (2.91 in) × 45 mm (1.78 in) and is listed at 135 g (0.30 lbs) with AA battery. The published grip guidance is Palm, Claw. Use those measurements against a familiar mouse; grip labels alone cannot predict comfort.

Good fit if

  • You already use Palm, Claw on a similarly sized shell.
  • You want a heavier mouse.
  • The Right-handed design matches your preferred hand position.

Consider another shape if

  • You cannot compare the dimensions with a mouse you already find comfortable.

🎯 Sensor & Tracking Quality — What You're Actually Getting

Sensor
Logitech Advanced Optical Tracking
The sensor model is the most useful identifier when comparing tracking hardware.
DPI Range
1000 DPI (fixed)
Maximum DPI is an adjustment range, not a promise of better aim.
Polling Rate
125 Hz
Higher polling can reduce the interval between cursor updates when the system supports it.

Logitech Advanced Optical Tracking is the listed sensor. 1000 DPI (fixed) sets the available sensitivity ceiling. 125 Hz is the stated polling range. The useful setting is the one that remains stable on your PC, receiver and mouse pad—not necessarily the maximum number.

🧩 Clicks, Buttons & Build Quality

Switches
Standard mechanical switches
Switch specifications identify the mechanism; sound and feel still require hands-on judgment.
Buttons
8 Programmable Buttons
Check placement as well as the total count.
Scroll Wheel
Hyper-fast scroll wheel with click-to-click mode and tilt for horizontal scrolling
Encoder type does not fully describe tactility or noise.
Shell / Body
Sculpted matte plastic with rubber grip
Material and construction affect mass and rigidity; coating feel is not inferred.

Switches: Standard mechanical switches. buttons: 8 Programmable Buttons. wheel: Hyper-fast scroll wheel with click-to-click mode and tilt for horizontal scrolling. body: Sculpted matte plastic with rubber grip. Treat feel, noise and long-term durability as untested unless a hands-on test is explicitly cited.

🔋 Wireless & Battery — What to Expect

Connection
Dual Connectivity - Bluetooth Smart and 2.4 GHz wireless via Logitech Unifying Receiver
Use wired or 2.4 GHz for latency-sensitive play; Bluetooth prioritizes convenience.
Battery Life
Up to 24 months per battery
Runtime varies with polling rate, lighting, sleep settings and battery age.
Charging
Replaceable battery (no charging)
Confirm cable and charger compatibility in the regional package.
Receiver / Dongle
Logitech Unifying Nano Receiver (USB-A)
Use the intended receiver for the advertised wireless polling modes.

Logitech M720 Triathlon supports Dual Connectivity - Bluetooth Smart and 2.4 GHz wireless via Logitech Unifying Receiver. The published runtime is Up to 24 months per battery.

👤 Who Should Buy This Mouse?

Buy if

  • You specifically want the Logitech Advanced Optical Tracking platform.
  • A 135 g (0.30 lbs) with AA battery mouse suits your handling preference.
  • Dual Connectivity - Bluetooth Smart and 2.4 GHz wireless via Logitech Unifying Receiver matches the devices you use.
  • Your grip and hand size match the Palm, Claw guidance.

Skip if

  • The 115 mm (4.53 in) × 74 mm (2.91 in) × 45 mm (1.78 in) shell is a poor match for your hand.

🛒 Practical Buying Advice

Before Buying

Compare 115 mm (4.53 in) × 74 mm (2.91 in) × 45 mm (1.78 in), 135 g (0.30 lbs) with AA battery, button placement and grip guidance with a mouse you already know.

Value Check

Judge value at the current regional price against mice with the same Logitech Advanced Optical Tracking, connection modes and warranty.

Best Configuration

Start at 1000 Hz and raise polling only if 125 Hz remains stable on your system. Set DPI for control rather than chasing the maximum figure.

What to Verify

Confirm the exact regional model, package contents, receiver, supported software and warranty before checkout.

Buying Call

Choose Logitech M720 Triathlon if its heavier weight, shape, connection options match your setup; otherwise prioritize fit over headline sensor numbers.

🏁 Final Verdict

Logitech M720 Triathlon: the fit matters more than the maximum DPI

Logitech M720 Triathlon's clearest strengths on paper are 135 g (0.30 lbs) with AA battery weight, Logitech Advanced Optical Tracking, 125 Hz and Dual Connectivity - Bluetooth Smart and 2.4 GHz wireless via Logitech Unifying Receiver. The deciding risk is fit: confirm the dimensions, grip style and software support before treating the specification sheet as a recommendation.
