It's being used in 24/7 mission critical systems. Make sure you carefully read instructions about variable obfuscation and decomposition, also be ready to increase default nesting levels as decomposed complex conditionals can get DEEP. Also use debug mode so you can see what it does to your code before it moves it to the dll- it's horrible.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more

the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
