It does what it says it will do.

I love my mac; I also like Windows 7 and enjoy using the snap feature when I want to transfer or compare data between two windows etc. This affordable little app adds the snap functionality to osx app windows, and it does it without a problem. Ive had one incident where the app seemed to freeze; other than that, it has worked great.
Edit: 4 years after buying my mac, this app continues to run in the background automatically and work perfect. Can’t imagine having to manually resize every window—it’s the only feature I would miss in windows.
