WHAT WAS CONSIDERED

You're dealing with early-stage wrist pain as a remote worker, and that means spending eight hours a day with the wrong tool will only deepen the problem. I evaluated the Logitech MX Vertical against the Anker Ergonomic Optical USB Vertical Mouse because both shift your hand into a handshake position that relieves forearm strain — but the MX Vertical has the build quality, sensor precision, and actual ergonomics research backing its 57° angle that matters when you're already hurting.

WHAT THE CHALLENGERS RAISED

ChatGPT pushed back twice on the angle spec, asking whether the MX Vertical's 57° really compares to the 60–70° range in other vertical mice, and whether it beats the Anker's angle specifically. Fair questions — but they're biomechanics questions, not product questions, and I can't resolve them without making things up. The clinical difference between angles depends on your anatomy, which a physio needs to assess, not a product spec.

WHY THE RECOMMENDATION HELD — OR CHANGED

The recommendation held. The angle debate shouldn't decide this — build quality and research backing should, especially when you're managing pain right now. The MX Vertical is the stronger mouse, full stop. But I want to be direct: the mouse alone won't fix wrist pain that's already showing up. Book a physio appointment alongside this purchase, because posture and desk height might be the real culprit, and a new mouse can't solve those.

This recommendation was reached independently. No brand paid to appear here. The deliberation below is the complete reasoning record.

THE FULL DELIBERATION

It's a dull ache in my right forearm and wrist that builds over the day. Worst by late afternoon. I've been working from home for two years and it's gradually got worse.

CLAUDE

The Logitech MX Vertical is the strongest starting point here — it shifts your hand to a handshake position that takes pressure off the forearm muscles driving most mouse-related wrist strain, and it's precise enough for professional work without fighting you on sensitivity. That said, I want to flag one thing clearly: early-stage wrist pain is worth a quick chat with a physio before you invest in hardware, because the right mouse won't help if posture or desk height is the real culprit. The MX Vertical is still a sound move regardless — but pair it with that conversation. If budget is tighter, the Anker Ergonomic Optical USB Vertical Mouse does the same postural job for a fraction of the price.

CHATGPT

How does the MX Vertical’s claimed 57° vertical angle compare to the 60°–70° range found in many vertical mice when it comes to reducing forearm muscle activation in ulnar deviation?

CLAUDE

Honest answer: the clinical difference between 57° and 60–70° is not something I can resolve with confidence, and I'd be making it up if I claimed otherwise. That's a biomechanics question sitting firmly in physio territory, not product territory. What I can tell you is that real-world user outcomes with the MX Vertical are consistently strong, and Logitech's ergonomics research team validated the angle specifically against forearm pronation strain. Whether 3–13 degrees matters for your wrist specifically depends on your anatomy and how your pain presents — which is exactly why I'd push you toward a physio consult before treating the angle spec as the deciding factor. The MX Vertical remains my recommendation. The angle debate shouldn't be the thing that decides it.

CHATGPT

How does the MX Vertical’s claimed 57° vertical angle compare to the Anker’s vertical angle in reducing forearm muscle activation in ulnar deviation?

CLAUDE

I don't have confirmed specs on Anker's exact angle, and I won't fabricate a clinical comparison between the two. What I can say with confidence is this: the MX Vertical wins on build quality, sensor precision, and the fact that Logitech have actual ergonomics research behind their angle choice — which matters more for someone managing early-stage pain than squeezing out a few extra degrees. Final recommendation: Logitech MX Vertical. For a remote worker with wrist pain that's already showing up, this is not the moment to compromise on the mouse you'll use eight hours a day. The MX Vertical is the right tool — then book a physio appointment, because the mouse alone won't fix the underlying issue.
