What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the ProtoArc EM11 NL has earned a notable amount of grassroots momentum on r/MouseReview, where multiple long-form user reviews directly compare it to the Logitech MX Vertical and conclude that the shape is at least comparable, with less palm drag for some grips and noticeably quieter main clicks. uk.pcmag.com has covered ProtoArc's vertical-trackball hybrid in the same family, which is the closest mainstream-press anchor in the candidate data. The headline draw across reviewers is connectivity: triple-channel pairing across two Bluetooth devices plus a 2.4GHz USB-A dongle, USB-C charging, and adjustable DPI levels, all at a sub-$25 price point.
What reviewers liked
- Multiple r/MouseReview long-form user reviews are positive on shape, switches, and quiet clicks
- Three-device pairing (2x Bluetooth + 2.4GHz) is a standout at this price
- USB-C charging and adjustable DPI levels are called out by verified-purchase reviewers
- r/ProtoArcHub and r/SamsungDex threads confirm broad cross-platform compatibility
Where it falls short
- No high-trust independent expert review of this exact SKU in the signals
- Sensor is budget-tier, not suited for precision or gaming work
- Newer brand with less long-term reliability data than Logitech or Anker
- r/MouseReview includes mixed feedback on palm drag depending on grip style

Caveats are honest. There's no high-trust expert review of this exact SKU in the signals, the sensor is budget-tier, and the brand is far less established than Logitech. As a multi-device productivity mouse on a tight budget, though, the consensus across community trust tiers is positive.

If your wrist is tired, your desk is cramped, and your pointer finger is ready for retirement, the ProtoArc EM05 NL might be worth a look. This curious little hybrid peripheral combines a thumb-controlled trackball with a vertical mouse shell, creating a rare ergonomic design…
It does a great job of keeping your hand in a nice position, glides easily, has relatively good click/button placements, and was plug-n-play out ...
This is a solid vertical mouse, especially given the price of just $26.99 (at the time of this post, September 2024). The battery life is outstanding.
