I've never had an issue in multiple seasons of cyclocross (check out the pic -- works flawlessly in mud!).
Setup can be tricky and may require multiple attempts to prevent chain rub in the big / small cogs.

I'd much rather use a clutch derailleur without a chain guide though. Much cleaner and no risk of chain rub.

As other commenters have said, the setup is tricky. There are two bolts and tightening them anchors the unit to your seat tube AND secures the position of the guide at the same time. This means that you can carefully align the guide only to pull it out of whack when you snug it up. If there was a separate bolt to secure the guide adjustment, it would be a breeze, but not so.
This is really a pain if you swap chainrings from time to time. If you don't tinker with your gearing, then setting it up once isn't too bad.
Side note...my frame has a boss for a deraileur cable pulley that prevents mounting this at the height it needs to be for a 44t ring (my usual setup). I had to grind the mounting hardware quite a bit for it to work. Not ideal for my frame.
PROS: Attractive Design
CONS: Difficult To Install
Setup requires you to be precise and ensure you check the extremes of your driveline to set up the best compromise for your cassette.
Compared to other components out there this is one of the better ones made for this job.
