I've developed a love-hate relationship with CoffeeBreak Pro, mostly because it does what it says it'll do: Lock up your machine and FORCE you to take breaks. I'm prone to arm, shoulder and neck aches from too much computing, yet I don't seem able to walk away from my machine when I'm fully involved in something unless I'm forced to. CoffeeBreak Pro is that force. It probably should be a little cheaper, and it definitely needs improvement on the screen-break graphics. On the overall, though, it's a good purchase for those who need more than a gentle reminder to take a break.
