It's ok, but it often suggests a single correction that is no where near the correct grammar. I understand it's still in development and will try it out again in the future, but for now it's less useful than Googles built in spell checker.

I'm so happy I don't have the Grammery keylogger installed anymore, it makes me want to cry.
