Great, but not for everyone
I've been using Magic Mouse for over 7 years now and have never had any major issues with that apart from one: it keeps disconnecting each time I slightly lift and put it back on the table (recently bought another one and it has the same issue).
It happens probably due to the way I'm handling the mouse and you might never experience this at all if you are gentle with it. It is also easy to reconnect back, usually takes only few seconds. But if you are handling the mouse in sort of 'aggressive' way (eg. in gaming or fast-peaced office environment) you might be disappointed with this one as it is not 100% reliable.
The whole surface of the mouse is made-up of a mini-trackpad that accepts all kinds of multitouch gestures which have various functions in MacOS. It all works very well and I found them useful for browsing internet, navigating documents, swapping between apps and other desktop tasks. The pointer is precise and stable – it helps in design apps such as Illustrator of SketchUp.
The mouse is also quite durable – been using a second-hand one bought of Ebay around 2010, still works and looks good. Easy to clean as it doesn't have any buttons, wheels etc. the surface might get scratched, though, as it is not as durable as the iPhone glass.
Summarising, I cannot imagine any other mouse in that price range for the Mac.
