Pretty Good

I would consider buying it if I did not read so many reviews about bugs and they had released and Update since for Yosemite. Since the last update was May 2014 it obviously has not been optimized for Yosemite and probably the reason it is buggy. If they want you to pay 15$ then they have to expect to support the product and no updates in 9 months does not cut it.
