Works about 20% of the time.

I use the feature this is supposed to implement in various distros of Linux all the time, so I really miss it in OSX and was excited to find this app. Unfortunately, it works only occasionally. You may grab a window, bang it up against the side of the screen over and over with no reaction from this app at all. Try the other side, and it works just fine. A minute later, it might work on the first try with the same window, or it might not. The end result is a drain instead of an improvement in productivity. This is the case with every browser, office app, video app, and finder window I try. I have since bought and installed a keyboard based app that has more advanced functionality. Now I try the Cinch method, it fails, and I use the keyboard to do what I should have done in the first place. The keyboard app has the added benefit that you dont lose screen edges with a multi-display setup.Get Divvy and save yourself some a few bucks and some frustration.
