it seems to work well enough. It's a great place to keep reference material... but a little cumbersome to compose a list on my phone. much easy on the desktop. Its web based and one time their server went "tits up" for two days... and i was unable to access it for the entire time it was out. Definitely a downside. It's free and now that they fixed the "online only" part it's my go to application.
I also use Colornote (for android) as a quick way to jot down a few things. Its only a phone app.
