Very natural to use in hand. Easy setup.
Color: Lavender
I love this mouse! I wear a size small in women's gloves (USA). This fits perfectly in my hand. The shape is so natural and restful. The color a is a clear pastel purple, a lilac, but not too bright or overly soft. It is a little darker than my screen showed, as the picture appears to have a bright light and reflections. Connectivity has been a breeze. No issues at all connecting to a Surface Pro 11. We'll see how it goes connecting to the 12 ... Doesn't fit in the Smatree brand hard carrying case for laptops...too tall. But I am keeping it for home use anyway. Eve I though I have one of those surface pro lays flat mice coming. Only time I needed a mousepad was one time when I tried to use it outside of my picnic table and there seemed to be little grit so I had to clean that off, and just I have a really loose really thin picnic table cover for the winter that I hadn't taken off yet and it did not like that. But it went on my tablecloth and my kitchen table. It worked on my kitchen counter. It worked on my office desk and it also worked on a mouse pad. I have only used it for about 3 days. Sometimes I would remember to turn it off when I wasn't using it and overnight. Sometimes I didn't. Haven't had to recharge it yet. Update: returned the refurb 11 and bought a new 12. my surface pro mouse came in. I paired it, used it for about fifteen minutes. turned it off. and paired this one. I had to cycle it through since it had been previously paired. This was no trouble at all and only a minute to do. it's too tall for some pockets, but my hand stopped hurting, so I'm going to try to use a separate storage case for accessories. it's radius for moving across the screen is helpfully small.

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!
