What Is the ProtoArc EM11 NL Mouse?
The ProtoArc EM11 NL is a compact vertical mouse that holds your hand at a 58-degree angle instead of the flat, pronated angle a standard mouse forces, and is specifically sized for hands under 7.5 inches. It's part of ProtoArc's "workspace for wellness" lineup alongside the EC200 chair and EK01 Plus keyboard — see our full desk setup comparison for how the three address different strain points.
How We Picked This
This isn't a hands-on trial. We picked the EM11 NL by checking its published angle and sizing specs (58 degrees, sized for hands under 7.5") against the actual mechanism vertical mice use to reduce wrist strain — moving the hand from a flat, pronated position toward a neutral handshake angle — plus its concrete connectivity and battery specs (dual Bluetooth 5.0 and 2.4G USB, a 500mAh battery with USB-C charging). We could not find an independent third-party rating platform for ProtoArc, so this page doesn't carry a verified satisfaction score — see the ratings section below. This is disclosed research, not an in-house multi-week usage trial — see how we test products.
Key Features
58-Degree Vertical Angle
The core mechanism is the angle itself: a standard mouse holds your forearm in a flat, pronated position for hours at a time, while a 58-degree vertical angle moves your hand closer to a neutral handshake position. This is the same underlying principle behind every vertical mouse, and the specific angle is a checkable spec rather than a vague ergonomic claim.
Sized for Hands Under 7.5"
ProtoArc specifically markets the EM11 NL's slim profile toward smaller hands, which matters because a vertical mouse sized for an average-to-large hand can feel awkward or unstable in a smaller one — this is a sizing detail worth checking against your own hand measurement before buying, not just the angle spec alone.
3-Level DPI (1000/1600/2400)
Three switchable DPI levels give you a working range from precise, slower cursor movement up to faster tracking, useful if you switch between detail work and general navigation rather than needing one fixed sensitivity.
Dual Connectivity, 500mAh USB-C Battery
Bluetooth 5.0 plus 2.4G USB connectivity covers most setups without needing a specific dongle type, and the 500mAh rechargeable battery charges over USB-C rather than a proprietary cable or disposable batteries.
Real Customer Feedback
We could not find an independent Trustpilot page or similar third-party review platform for ProtoArc, and the EM11 NL's own product listing doesn't surface a visible aggregate rating or review count in its page data as of this writing. That's a genuine gap — we can verify the published angle, sizing, and battery specs, but not an independently confirmed satisfaction score from a meaningful sample of buyers.
Pricing & Where to Buy
ProtoArc sells directly through its own Shopify storefront, so there's no marketplace Buy Box to compare — this listing's price has moved before (it was closer to $22.99 in prior months), so treat the figure above as a snapshot, not a fixed number, and confirm the live price before buying.

ProtoArc EM11 NL Mouse Pros & Cons
Pros
- 58-degree angle and small-hand sizing are checkable specs, not vague ergonomic marketing
- Compact size makes it the most travel-friendly of ProtoArc's three current products
- 3-level DPI covers both precision and faster-tracking use cases
- USB-C rechargeable battery avoids disposable-battery cost and proprietary cables
Cons
- No independent third-party rating platform found to verify buyer satisfaction
- Vertical mice generally involve a short adjustment period for cursor precision compared to a standard mouse
- Small-hands sizing means it may feel undersized for larger hands — check the 7.5" guidance against your own hand before buying
Who Should Buy the ProtoArc EM11 NL Mouse?
Anyone whose specific discomfort is wrist strain from clicking and scrolling rather than typing or sitting posture, especially if you have smaller hands that a standard-sized vertical mouse doesn't fit well. Its compact size also makes it the practical pick of ProtoArc's three products if you need ergonomic gear that travels well.
The ProtoArc EM11 NL Mouse is NOT right for you if: you have larger hands — ProtoArc specifically sizes this for hands under 7.5", and a mouse sized too small for your hand can undercut the ergonomic benefit the angle is meant to provide.
Other Home & Lifestyle Picks
If this isn't quite the piece you need, here's what else we're currently featuring in ProtoArc's lineup and the wider category:
- ProtoArc EC200 Chair — for back or hip pain from long sitting
- ProtoArc EK01 Plus — for wrist and hand strain from typing rather than clicking
- All Home & Lifestyle Picks — browse the full category
Final Verdict: Is the ProtoArc EM11 NL Mouse Worth It?
The EM11 NL's case rests on two concrete, checkable specs — a 58-degree angle and small-hand sizing — plus genuinely useful connectivity and battery details, not a verified review score. If wrist strain from clicking is your specific issue and your hand fits the under-7.5" guidance, it's a reasonably priced way to address that one problem, though we can't back the recommendation with independent buyer-satisfaction data.
