ESR MagMouse Review

ESR has introduced the MagMouse at CES 2025 as the world’s first magnetic mouse with a built-in charging cable. What’s immediately obvious is its compact size relative to the competition. It’s been three weeks since I’ve been testing the ESR MagMouse to see how good it is, and honestly, I really like what this product brings to the table. However, the mouse is certainly not without its limitations. Read on to our in-depth review to find out if this is a compelling affordable option or not.

Unboxing

Price and Availability

The ESR MagMouse is now available via the company’s Kickstarter for $36. ESR offers three color options for the gadget, including white, gray, and black. 

Design and Build 

When I unboxed the ESR MagMouse, I was taken aback by its compact and lightweight form factor. To be more precise, the mouse measures 107.5 x 64 x 38.9 mm and weighs just 75 grams. What I liked most about the MagMouse is its ergonomic design, although it isn’t specifically marketed as an ergonomic mouse. Still, it perfectly fits in my hand and feels quite comfortable during long work sessions without causing fatigue. 

Unlike other inexpensive mice, the ESR MagMouse has a hard plastic build, but what sets it apart is its soft-touch-like coating, which is rare to find in mice at this price range. No doubt, the plastic build feels slightly cheap, but I can confirm it’s sturdy and durable. One of the most innovative things about the MagMouse is its built-in charging, which sits beneath the mouse alongside a 2.4 GHz USB-A adapter. The MagMouse has a total of seven buttons: four on the top, two on the right side, and one on the bottom side. All buttons are quiet and feel very responsive. 

Lastly, it also ships with a magnetic attachment system, which is a primary selling point and a standout feature of the mouse. The magnetic base is impressively thin at just 4.8 mm and easily sticks to any laptop surface while holding a magnetic strength of 700 grams. Speaking of practical usage, I tried it with the Lenovo LOQ laptop, and interestingly, the base firmly holds the mouse in place even when moving between one workplace and another. This magnetic system comes in handy for office people, who are constantly moving from meeting room to meeting room. 

Performance 

While the mouse doesn’t have every single feature of the premium productivity mice, such as the Logitech MX Anywhere 3S, it still does a decent job for its price. The ESR MagMouse features six adjustable sensitivity levels ranging from 800 to 4800 DPI (dots per inch). During my testing, I found this DPI range sufficient for intermediate tasks like photo/video editing and browsing. 

One thing that I liked is the four-way functionality of the middle scroll wheel. I found the scroll wheel very smooth and responsive, especially when scrolling through websites and documents. Plus, you can also side-scroll with the scroll wheel, which lets you glide effortlessly across wide images, spreadsheets, and wide documents, and it works flawlessly. The optical sensor responded accurately on most surfaces, and there were no tracking issues or slowdowns.

The two buttons on the right side bring great convenience by offering back and forward functions with a web browser. Unfortunately, ESR doesn’t offer any software for the mouse to reconfigure buttons. 

Connectivity and Battery Life

The ESR MagMouse offers dual connectivity options: Bluetooth 5.0 and a 2.4 GHz USB-A dongle that sits in the base of the mouse. The mouse is compatible with everything from Windows and MacBooks to iPads and Android tablets. During testing, I didn’t encounter any connectivity issues whatsoever. However, the only quibble I have is that it lacks a multipoint connection, which is slightly disappointing. There’s also a three-way slider button located at the bottom of the mouse, allowing you to switch between Bluetooth and 2.4 GHz connectivity.

Inside, the MagMouse has a 500 mAh battery, and the company claims it lasts up to 160 hours. Honestly, the battery life of the mouse is really impressive, and it performed as advertised. During my three weeks of testing, I haven’t charged the mouse a single time, and it still goes on. What sets the ESR MagMouse apart from other mice is its innovative built-in charging cable. 

Yes, it has a small 2-inch built-in USB-C charging cable at the base, which brings great convenience, and you don’t have to worry about the correct charging cable for it. 

It also has fast-charging support; a one-minute charge offers you four hours of working time, which is great, while the mouse takes around 45 minutes to hit the 0 to 100% mark and offers 160 hours of battery life. Well, despite its integrated charging cable, there’s a quibble. The embedded charging cable is too short, which doesn’t allow you to use the mouse comfortably while charging. Although it sports fast charging, I don’t think it’s a major problem.

Final Thoughts

Overall, ESR did a fantastic job with MagMouse. The innovative mouse has everything from a lightweight and sturdy build to six adjustable sensitivity levels, a four-way scroll wheel, and a solid 160 hours of battery life, and surprisingly, it doesn’t cost a fortune. While it doesn’t have multiple device pairing and reconfigurable buttons like other premium mice, its innovative magnetic attachment system, embedded charging cable, and great versatility to work in most workplaces make it a stellar option for casual users.
