You can now get a slim wireless mouse from Logitech that changes shape. It’s called the Pebble Up, and it can either lie flat or raise the top shell for a more comfortable grip when you need it. It follows the Pebble Mouse 2 M350s, which Logitech introduced alongside the Pebble 2 keyboard in 2023.
The Pebble Up measures 105.8 x 59.6 x 30 mm and weighs 79 grams. By comparison, the Pebble Mouse 2 M350s weighs 76 grams, so the extra height and second shape add very little weight.
Logitech Pebble Up Specifications
Inside you get an optical sensor with 4,200 CPI resolution and an adjustable DPI range from 400 to 4,000. There are four buttons: left click, right click, the scroll wheel button, and a DPI button.
As expected from a Logitech mouse, you can reprogram the scroll wheel button and the DPI button in the Logi Options+ app, which also supports a gesture function. The scroll wheel is segmented, so it scrolls in steps.

The Pebble Up uses a 290 mAh rechargeable lithium polymer battery that Logitech rates at 90 days per charge. That’s a change from the AA battery in the Pebble Mouse 2 M350s.
You can connect it via Bluetooth Low Energy or through a Logi Bolt USB receiver, and you can pair it with up to three devices and switch between them with Logitech’s Easy-Switch. It offers a wireless range of 10 meters.
Logitech uses Logi Options+ for AI tools on this mouse. The app runs on Windows and macOS. On iPadOS, Linux, ChromeOS and Android you get the basic mouse functions without customization. Logitech used the same app to customize buttons on previous mice, such as the POP mouse, which has two programmable action buttons.


The Pebble Up comes in Rose Pink, Graphite Gray and Pearl White. All colors use certified post-consumer recycled plastic. Rose Pink and Pearl White contain 43% recycled material, and Graphite Gray contains 56%. The mouse comes with a one-year limited hardware warranty.
The Logitech Pebble Up is priced at 250 Yuan (~$37).
