Bluetooth Arc Touch Mouse, Slim Portable Mini Wireless Computer Mouse Without USB Nano Receiver, Folding Optical Mice for Laptop Notebook Tablet - Black

very responsive and can fit anywhere, so small.

Unfortunately I found the tracking was not stable, as you move the mouse or scroll with scroll wheel it did not stabilize on the selection but would move around a bit...lower quality than others i have had.

Quality of the Microsoft Arc Mouse, one fifth the price.

Works well

I like the mouse. It worked out of the box and was easy to connect to MacBook. My only complaint is the scroll wheel. It works but barely. If you plan to use the scroll wheel don’t buy but you probably don’t need a scroll wheel anyway.

Mouse does not track consistently.

Nice build quality and tactile feel, but "mouse" controls cursor unreasonably fast. While a mid-range setting of mouse speed control panel works well with real Microsoft product, this mouse requires control panel setting at minimum to not be "flighty" across the screen. It would be very nice to have dot or pixel rate adjustable on this unit itself.

I work in IT so I'm kind of a hardware nerd (snob?). I used a very nice rechargeable mouse for years and loved it, but as it was a full-sized gaming mouse, that's not really practical to pack in a laptop bag to take to training or a meeting. As my company is sending me off to a conference this fall (Yay!) I needed a mouse like this. Years ago I had one of these Arc Mice (I think Microsoft was selling them?) and I really liked that mouse - until someone swiped it from me. I still really like the design of these where it stores flat (and is powered off when flat) but with a simple flex of the mouse you're in business and working. For less than $25 I have a stylish mouse that packs flat and works really well.
