I've had a few ergonomic mice before, but this one is the most comfortable so far. It's responsive and accurate. It's also nice that you can simply charge it, so no more battery hassles. (I've had this one for over two weeks now and haven't had to charge it yet...)

I've been using it for a week now and I'm very pleased with it. I haven't had to charge it yet.

Due to carpal tunnel syndrome and joint problems, a regular mouse doesn't work well, but this is a relief! A natural posture, no pressure on the inside of your wrist. Suitable for medium to slightly larger hands (depending on which buttons you use most often). With this mouse, I can still enjoy casual gaming without pain! Bluetooth: Connects once, then automatically. If the dongle isn't in use, it's not necessary, but it stays safely stored under the cover just in case.

Our digital expert will help you, but it can sometimes make mistakes, like humans do.
According to our mouse expert
Work comfortably: the ergonomic design keeps your arm, hand, and wrist in a natural position.
More freedom of movement: because the mouse is wireless, you can use it anywhere.
Keep a USB port free: thanks to Bluetooth, you can connect the mouse to your computer without a USB dongle.
No fast scroll wheel: scrolling through large spreadsheets and long pages takes more time.
No horizontal scrolling: you'll navigate spreadsheets and pages less easily without a horizontal scroll wheel.

How large is a mouse exactly? It's often difficult to see on a photo. That's why we thought of the thumb rule below.
Choose a mouse that takes up more than half of the surface of the dimensions of your hand. You can find the dimensions of the mouse under the specifications.
Your hands are often 2 times longer from your wrist to the tip of your middle finger than that it's wide from your little finger to the knuckle of your thumb. The closer the length and width a mouse come to 60% of the length and width of your hands, the more likely it is that the mouse feels comfortable in your hand.
