Great general purpose, inexpensive mouse.
Color: Grey
For the price, it’s an outstanding mouse. Have only used Bluetooth mode, and only used it for basic computer operations (not gaming), but feels responsive and comfortable. Great battery life.

A great mouse for the price.
Color: Grey
This mouse is a great value and works well! It was extremely easy to connect to Bluetooth on my Microsoft Surface. I have also used it connected via the included dongle to my home PC.
The USB type C charge port is really appreciated to minimize the number of cables that need to be carried to charge everything. It lasts a great amount of time between charges.
My only minor complaint is that my large hands have a bit of difficulty holding it. I understand that it is a portable mouse intended to take on the go, so I didn't knock of anything for that.

Great mouse and best customer service ever!
Color: White
I bought this mouse a few months ago, and initially, I was quite happy with it. The design felt comfortable, and it worked smoothly right out of the box.
However, after a few months of use, I started facing an issue with the clicks. Sometimes a click wouldn’t register at all, and other times it would register as a double-click, which became pretty frustrating during regular use.
I decided to reach out to the company via email, and that’s where the experience really turned around. Their response was quick, the communication was crystal clear, and the whole process was smooth and hassle-free. Without much back-and-forth, they immediately sent me a replacement mouse.
I’ve been using the new mouse since then, and it has been working flawlessly with no issues at all.
Overall, while I did face a problem initially, the excellent customer support and the performance of the replacement have left me very satisfied. Highly recommend this mouse!
