Bottom line: The ProtoArc EM01 NL Wireless Trackball Mouse ($37.99 on Amazon as of 2026-10-07): 0-20 degree hinge tilts the trackball to your natural hand angle; main trade-off: scroll wheel and side buttons are not silent, unlike the main clicks.

Manufacturer description

The ProtoArc EM01 NL is a thumb-operated wireless trackball mouse built for desks where you cannot swing a mouse around. You move the cursor with your thumb on the ball instead of dragging your whole arm, so it works on a crowded desk, a couch armrest, or a bed tray. The 0-20 degree hinge lets you tilt the trackball to match how your hand naturally rests, which matters over a full workday. Five DPI steps - 200, 400, 800, 1200 and 1600 - let you drop to fine tracking for spreadsheet cells and jump up for multi-monitor sweeps. Connectivity covers both Bluetooth and 2.4G wireless, and you can…

SpecPicks Verdict

SpecPicks scored ProtoArc EM01 NL Wireless Trackball Mouse using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. ProtoArc's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for gaming peripherals of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How does the ProtoArc EM01 NL connect to my computer?

Two ways: Bluetooth or the 2.4G wireless mode. You can pair up to three devices at once and switch between a PC, laptop, and tablet with a single button.

What DPI settings does this trackball support?

Five levels - 200, 400, 800, 1200, and 1600 DPI - cycled on the mouse so you can slow down for detail work or speed up across large displays.

Is the ProtoArc EM01 NL actually quiet?

The left and right clicks are quiet, which is the point in a shared office. ProtoArc notes the scroll wheel and side buttons are not silent, so it is not fully noiseless.

Does it take batteries or does it recharge?

It has a built-in rechargeable battery, so there are no disposable batteries to swap. Check the product listing for current runtime and charging port details.

How long does it take to get used to a thumb trackball?

ProtoArc says most users adapt within one to two weeks. The tilt hinge helps - adjust the ball angle between 0 and 20 degrees while you find a comfortable grip.

Key Features

  • Adjustable Trackball Comfort: The 0-20 hinge lets you set the trackball angle to match your hand position, supporting a more natural grip through long work sessions
  • Thumb-Control Precision: Navigate documents and web pages by moving the thumb trackball instead of your whole arm, making it easier to work on crowded desks, couches, or beds
  • 3-Device Wireless Control: Bluetooth and 2.4G wireless modes let you connect up to three devices and switch between PC, laptop, and tablet with one button
  • Rechargeable 5-DPI Tracking: The built-in rechargeable battery avoids disposable battery swaps, while 200/400/800/1200/1600 DPI levels adjust cursor speed for different tasks
  • Quiet Shared-Space Clicks: Quiet left and right clicks and a frosted surface support focused work in offices or home spaces; scroll wheel and side buttons are not silent
  • Easy Trackball Maintenance: Clean the trackball and three white rollers after extended use to help keep movement smooth, especially after startup or heavy app loading
