It's pretty good. However, if you're willing to pay a lot more for similar functionality but with added flexibility, take a look at Divvy. But without a doubt, Magnet is more than worth its asking price.

Need an iBooks version.

It's beautiful. I wished there was an option to control the size (although to the design does allow for a simpler and smaller list view only). But no doubt, it's a huge improvement of the older, skeumorphic UI that's looking completely outta place on a Mac.
