AI Verdict
A 44mm index-finger trackball mouse with 5 adjustable DPI and 3-device connectivity, best for users needing an ergonomic, stationary input device on a budget.
This trackball is a situational fit because its ergonomic design and 3-device connectivity are compelling for specific use cases like wrist pain relief or multi-device setups. However, limitations like non-programmable buttons and potential coating degradation mean it won't suit everyone.
If this doesn't quite cut it, look for trackballs with software-programmable buttons and a more durable, hard plastic finish.

Pros

- Features an ergonomic design with a 44mm index-finger trackball, intended to reduce wrist pain and muscle stress.
- Operates effectively in small workspaces due to its stationary trackball design, eliminating the need to move the mouse itself.
- Includes a built-in rechargeable battery, rated to last up to 45 days on a single charge.
- Offers 5 adjustable DPI settings (200/400/800/1200/1600) for precise cursor control.
Cons
- The DPI adjustment button is inconveniently located on the bottom of the mouse.
- Forward and backward buttons are not compatible with macOS.
- Buttons are not programmable, limiting customization for specific workflows.
- The M505B model features a 'grippy material' coating that some users report may degrade over time.

Dimension Scores
The 5 adjustable DPI settings (up to 1600 DPI) provide adequate precision for general use, and users report smooth tracking without stiction.
Its ergonomic shape and 44mm index-finger trackball aim to reduce wrist strain, but some users find the overall size a bit small for their hands.
Offering both Bluetooth and 2.4G USB connectivity with the ability to connect to and switch between three devices is above average for its price point.
While the ball movement is smooth, the M505B's 'grippy material' coating raises concerns about long-term durability and potential degradation.
Best For
- Users experiencing wrist pain or seeking an alternative to traditional mice for comfort.
- Individuals with limited desk space who need a stationary input device.
- Multi-device setups (e.g., switching between a PC, laptop, and tablet) due to 3-device connectivity.
- Budget-conscious buyers looking for an index-finger trackball mouse.
Not Recommended For
- Mac users who rely on forward/backward mouse buttons for navigation.
- Users requiring programmable buttons for custom shortcuts or gaming.
- Those who prefer a larger trackball mouse or a smooth, non-coated surface.
Watch Out For
- The advertised 'up to 45 days' battery life can be significantly shorter for heavy users, with some reporting less than a week of use before needing a recharge.
- The M505B model's 'grippy material' coating has been compared to older electronics that 'will slowly turn to goop' over time.
- The DPI switch is located on the underside of the mouse, making on-the-fly adjustments awkward and disruptive.
- Some users report that the left click can accidentally trigger if the device is picked up.
- The scroll wheel's middle click can feel 'not quite perpendicular to the wheel axis' for some, leading to an off-axis click sensation.

What Buyers Say
Many users are switching to the Nulea M505B from more established brands like Logitech, citing smoother feel and better ergonomics for wrist comfort. However, the battery life often falls short of the advertised 45 days, especially for heavy users who report needing to charge it weekly. The lack of programmable buttons and the inconveniently placed DPI switch are recurring frustrations. The 'grippy' coating on the M505B model is a point of concern for its long-term durability.
“I bought this to save my wrist, and it mostly does, but seriously, the battery dies so fast if you actually use it all day, and why is the DPI button on the bottom?!”
Common Praise

- Comfortable hand position for many users, reducing wrist strain.
- Seamless switching between up to three connected devices (Bluetooth and 2.4G USB).

Common Complaints
- Battery life is significantly shorter than the advertised 45 days for heavy use, sometimes lasting less than a week.

Ownership Tips
- The 'grippy material' on the M505B model feels like older electronics and might become sticky or degrade over time.

Buying Guide
When you're looking at trackball mice, you're usually trying to save your wrist or desk space. The big thing is whether you want to control the ball with your thumb or your index finger; this one uses your index finger. Also, check the connectivity options to make sure it works with all your devices, and don't just trust the advertised battery life if you're a heavy user.
Trackball Sensor (Index Finger Control)
This means you move the cursor by rolling a ball with your index finger, not by moving the entire mouse. It's stationary, which is great for small desks or if moving your arm causes discomfort.
5 Adjustable DPI (200-1600)
DPI (Dots Per Inch) controls how fast your cursor moves across the screen relative to how much you roll the trackball. More DPI means less physical ball movement for the same cursor distance, which is useful for precision tasks or large monitors.
3 Device Connection (Bluetooth, USB)
This lets you pair the mouse with up to three different devices (like your desktop, laptop, and tablet) and switch between them with a button, so you don't need multiple mice.
Ergonomic Design
This isn't just a buzzword; it means the mouse is shaped to fit your hand more naturally, aiming to reduce strain and discomfort, especially if you use a mouse for long periods.
Alternatives
If this trackball doesn't fit, look for models with software-programmable buttons, a larger overall size for better hand fit, or a hard plastic finish instead of a 'grippy' coating.
