Top critical review
Stylish, functional, expensive Carpal Tunnel device
Reviewed in the United States on December 19, 2018
It's beautiful, works out of the box (just like you'd expect Apple products to work) and brings a lot of handy features. You can read all about that from the other 5-star reviews, internet so I won't repeat any of that here.
This review is solely about what doesn't work - ergonomics. The design is not palm friendly and a few mins of usage will bring you pain as no other mouse has. To fix this, you need to make some additional investments - in the form of widening grips ASIN:B01MT7EN0F and a foam pad (google for Magic Mouse Fixed) that adds the palm-friendly contour to the mouse (see attached screenshot). I just got my foam but found it wasn't sufficient - you need the widening grips too.
Another feature that is highly annoying is that the back of the mouse also acts as a touchpad, so every time you try to click a link and your finger touches the surface, the web page will scroll a little. This little jump will make you miss the link as you need to move the mouse cursor to the new point or undo the scroll. As workarounds, you can lower tracking sensitivity or not use the touchpad feature at all - at which point you wasted 100 bucks for a glorified dumb mouse. The foam and the widening grips can alleviate this issue as they prevent the contact from happening.
So go ahead and spend 100 bucks on a stylish mouse, then spend around 30 bucks more in fixing it and you'll have the best mouse in the world. Or you can save those 100 bucks, and use the extra bucks to buy another Bluetooth mouse that will be little less smooth and not so sexy looking but will work just fine and not give you Carpal Tunnel.
