I don't like giving such low ratings, but this addon just isn't ready for production websites. There are a list of issues I've brought up (look at posts #38-41 of the discussion thread) that have not been addressed and don't look like they ever will be. There's been no considerations made for mobile users, so out of the box you'll have a big crazy looking button taking up real estate space from this addon. The code is also broken and doesn't track html elements properly so the 'hints' don't appear where they are supposed to if you move the screen even the littlest bit, it breaks completely. With all due respect to the author of this addon, I can't recommend anyone use this, much less pay $30 for it. I've removed it from my website since my user retention has actually tanked by 50% since I started using it, since it seems to bring up more roadblocks than it solves.
