This is the best mouse I have ever used. It was very quick for pairing and dummy proof. I don't know why anyone would give this mouse less than 5 stars unless you plan on using older electronics. I got my mouse yesterday and bent it to make it arch and then on my surface pro 2017 I went to settings then bluetooth settings added the device and it showed up and I just got the two paired and that was it. Now I can use the mouse on any surface. Now I use it on my bed and it still works. I know it's silly, but I love working in my bed because it's so comfortable. But the mouse fits perfectly in my palm and pops off easily, flattening the mouse for easy storage. I also bought a hard case so I can put it in my backpack and take it to work without worrying about damaging it. I can't say anything negative about the device. It works as advertised and I love the fact that you can scroll horizontally and/or vertically just by touching the front of the mouse. I like that it doesn't have a scroll wheel. I give this device 5 thumbs up if you can afford it. Since it uses BT in your SP or Surface device, you don't have to worry about carrying the key around and losing it. It also saves a USB slot for something else. Scrolling is just magic. It is very sensitive and each page flips through very easily. I like it. It fits my Surface Pro 2017 perfectly!
