Logitech MX Vertical Review: 6 Months of Daily Use for RSI Prevention

I switched to the Logitech MX Vertical after 4 months of growing forearm discomfort — specifically the outer forearm between the elbow and wrist that flared up after 4-6 hours of mouse use. A physiotherapist identified it as pronation-related forearm strain, not carpal tunnel, and recommended a vertical mouse.

After 6 months with the MX Vertical: the forearm discomfort is gone. Completely. I can use the mouse for 8+ hours without the same symptoms returning.

The Adaptation Timeline

Week 1: slow and frustrating. Cursor felt uncontrolled. Precision clicks (hyperlinks, small buttons) required conscious attention. Estimated productivity reduction: approximately 15%.

Week 2: cursor control improved but still required attention. Clicking precision back to near-normal. Fatigue in the thumb from gripping differently.

Week 3: transition point. Mouse started feeling natural. The grip pattern was no longer conscious.

Week 4: MX Vertical felt as natural as a standard mouse. No conscious adjustment during normal use.

If you try the MX Vertical and return it within 2 weeks because it feels unnatural: this is the expected experience, not a sign the mouse is wrong for you.

The 57-Degree Angle in Practice

Logitech markets the MX Vertical's 57-degree angle as placing the forearm in a "handshake position" that reduces muscle activity. This is accurate in principle — forearm pronation (palm down) requires sustained muscle activation that the neutral position does not.

After the adaptation period: the forearm rests in a naturally supported position on the desk surface. The mouse body supports the weight of the hand without requiring the forearm muscles to hold the pronated position.

The practical result: after 6 months, forearm muscle fatigue (the sensation of tired arms after long sessions) is significantly reduced. This matches the physiological explanation.

Cursor Control: 4000 DPI Reality

The MX Vertical ships configured at 400 DPI by default. At 400 DPI, the cursor moves very slowly relative to physical movement — this requires larger mouse movements, which is counterproductive for an ergonomic mouse.

Immediate recommendation: open Logitech Options+ and set DPI to 1600-2400. At 1600+ DPI, cursor response matches a standard office mouse at their typical 1000-1200 DPI setting.

The higher DPI reduces physical mouse movement per cursor unit, which reduces the total wrist and arm movement during a session. This is a secondary ergonomic benefit beyond the pronation angle.

Button Layout

The MX Vertical has 4 buttons: main click, right click, scroll wheel click, and a DPI switch button on the thumb side. This is functional but minimal.

The missing element: the MX Master 3S (standard horizontal mouse) has a horizontal scroll wheel and additional thumb buttons. The MX Vertical sacrifices these for the vertical form factor.

If you use horizontal scrolling or rely on thumb buttons: this limitation is noticeable. For standard point-and-click office work: the 4-button layout is sufficient.

Battery Life

Bluetooth operation for approximately 4 months on a full charge (approximately 200 hours of active use). USB-C charging, compatible with the same cable as modern phones and laptops.

Charging takes approximately 2 hours for a full charge. No option to use while charging (no wired mode).

Would I Recommend It?

For users with forearm pronation strain: yes, unequivocally. The MX Vertical directly addresses the mechanical cause of that specific discomfort, and the results were complete symptom resolution in my case.

For users with carpal tunnel symptoms: vertical mice are less likely to help because carpal tunnel is caused by wrist flexion during mouse movement, not forearm pronation. A trackball may be more appropriate.

For users without current symptoms who want prevention: the ergonomic benefit is real but harder to quantify when there is no existing discomfort. If you already use a good desk setup and wrist rest: the incremental benefit is smaller than for users with active strain.

For users with small hands: the MX Vertical is large. At 20.3cm length and fits best for hand sizes 18cm+ (measured from wrist to middle fingertip). Small-handed users may find the grip uncomfortable.
