Comfortable, Bluetooth works well, can't fault it.

Can't even use this mouse - only works (and even then, intermittently) on one type of device (Windows 10 Laptop) and only 1 or 2 times out of 10. Android 12 Phone? No. Raspberry Pi (KDE Manjaro) with internal BT and tried with a USB BT adapter. No. Piss me off coz it was a minor purchase a while back, receipt no longer existent, and it doesn't even have enough heft to it to serve an honorable but dual purpose as a paper weight. I might throw it at the neighbour or something, get some sort of use out of it. He kicked my dog.

Works ok for my MacBook Air 2018. But it turns off every 3 minutes if you’re not using it n you have to click to turn it back on. A little annoying if you’re trying to read an ebook. I would say it is worth buying a more expensive mouse that is better quality
