An occasional missed click is frustrating; a repeatable input interruption is a problem you can investigate. Reducing missed clicks starts by separating the physical parts of the setup from the game or application where the failure appears. Test one connection change at a time, note exactly which input is affected, and avoid treating every fault as a reason to change sensitivity or buy another mouse.

Quick Answer

Missed clicks can come from a shifting grip, dirty button gaps, loose USB contact or conflicting software. Reproduce the fault outside the game, test one connection change at a time and document whether the problem affects one button or every input. The R149 MARVO M291 has heavy-duty Omron switches in its product specification, but the correct response to a fault is evidence from a controlled test, not an invented lifespan.

🔎 Describe the fault before changing anything

Write down what happens. Does one primary button fail to register? Does a held drag release early? Does the whole mouse stop responding for a moment? Does it happen only in one game or also when selecting files on the desktop? Each description points to a different next test.

Reproduce the action in a simple local setting. Click a folder, drag a window, scroll a document and use a basic menu. If the mouse behaves normally outside the game, inspect the game settings, bindings and background applications before assuming there is a hardware defect. If the same button fails everywhere, continue with the physical checks.

🔌 Check the connection and surface methodically

Disconnect the mouse, inspect the cable route for a tight bend or a place where it may be crushed, then reconnect it to another USB port. Test again with the same local action. If another computer is available, repeat that small test there. Do not change ports, clean the mouse and alter software settings all at once; one change produces a result you can understand.

A wired mouse needs enough slack to travel across the pad without being pulled back by a desk edge. Clear crumbs and loose dust from the surface, then check the underside for debris around the skates. The gaming mouse pads range is useful when the current surface is too rough, cramped or dirty for a fair tracking test.

🧹 Clean only the accessible areas

Unplug the mouse before cleaning. Use a soft dry brush around the outside of button gaps and the wheel opening, then wipe the shell with a dry microfibre cloth. For an outer mark that remains, use a barely damp cloth corner and dry the area immediately. Never spray liquid directly into the mouse or push hard tools into a seam.

Cleaning can remove surface debris; it cannot diagnose every internal fault. After the mouse is dry, repeat the same click and drag test. If a repeatable issue remains on another USB port and another PC, record the exact button, action and result. That record is useful if you need a support process.

🧭 Separate grip problems from input problems

Some missed actions are not electronic failures. A tense grip can move the hand away from a side button, and a cramped desk can cause the cable to pull during a turn. Try the same action slowly with the wrist neutral and the palm resting naturally. If it works slowly but fails only during a rapid movement, review reach, surface space and the binding location.

The M291 lists six programmable buttons, so test side controls separately from the main clicks. Do not assign a high-risk action to a side control that your thumb reaches only by shifting the hand. A simple map with one reliable extra command is more useful than several bindings that create uncertainty.

The gaming mice category can help compare layouts if the real issue is fit. Start with the controlled tests first, because they prevent a temporary cable or surface problem from being mistaken for the wrong mouse shape.

Frequently Asked Questions

How can I tell whether a missed click is game specific?

Repeat the action in a desktop menu or local program. If the click works normally there but fails only in one game, inspect that game settings and bindings before changing hardware.

Should I clean a mouse that starts missing input?

You can remove loose debris around accessible gaps with a dry soft brush. Then test the same action again; cleaning should not involve spraying liquid or opening the mouse.

What should I write down for support?

Record the affected button, the exact action, whether it happens on another USB port or PC, and whether it occurs outside the game. A repeatable description is more useful than a general complaint.

Can DPI cause a missed click?

DPI changes pointer travel, not whether a button registers. A changing grip or an awkward side-button assignment can feel like an input failure, so test the physical reach separately.
