AI Verdict
A 2.26-ounce optical mouse with 4000DPI and dual BT5.0/3.0 + 2.4GHz connectivity, designed for users needing to switch between two devices.
This mouse is a situational fit due to its dual-mode connectivity (BT5.0/3.0 + 2.4GHz) and 4000DPI optical sensor, which are useful for switching between two devices. However, its compact size and lack of Mac compatibility for side buttons limit its appeal for certain users.
If you need full functionality on a Mac or have larger hands, look for a mouse with universal button compatibility and a larger, more accommodating ergonomic design.

What Buyers Say
Users frequently highlight the mouse's ability to connect to two devices and switch between them easily as a major convenience. The adjustable DPI up to 4000 is also a commonly praised feature for its precision. However, a recurring complaint is the lack of functionality for the back/forward buttons on Mac, which can be a dealbreaker for some Apple users. There are also scattered reports of quality control issues, such as units being dead on arrival or having problems with the battery compartment.
“This mouse is okay if you're on a budget and only use Windows, but seriously, the side buttons not working on my MacBook is so annoying, why even say it's for Mac then? And I had to return the first one because the battery door was messed up.”

Buying Guide
When picking a mouse, you need to think about how you'll connect it and what you'll use it for. If you're constantly jumping between a laptop and a tablet, multi-mode connectivity is a game-changer. Also, consider your hand size; a mouse that's too small will cramp your hand over time.
DPI (Dots Per Inch)
DPI tells you how sensitive the mouse sensor is. A higher DPI means the cursor moves further on screen with less physical mouse movement, like having a faster car. For precise work or gaming, you want higher DPI, but for everyday browsing, lower DPI is fine.
Connectivity (Bluetooth vs. 2.4GHz USB Wireless)
Bluetooth connects directly to your device without a dongle, freeing up a USB port, but can sometimes have slight latency. 2.4GHz wireless uses a small USB receiver for a more stable, often faster connection, but it takes up a port. This mouse offers both, giving you options.
Ergonomic Design
This refers to how the mouse fits your hand. A well-designed ergonomic mouse reduces strain and discomfort during long use, like a comfy chair for your hand. If it's too small or shaped awkwardly for you, it can lead to pain.
Alternatives
If you need a mouse with full functionality for macOS, look for models that explicitly support programmable side buttons on Apple systems. For larger hands, prioritize mice with larger dimensions and a more pronounced ergonomic curve.
