My buddy is gigging one right now and absolutely loves it. He did some kind of creative patching and looping with it, but so far so good. Said the compressor is one of the best he's heard, and prefers the distortions to that of the amp he uses (Marshall combo).
I have the tremolo version and I love it. It's great for when you want a small grab-and-go board with a reasonable amount of features. I really like the overdrives as they can cover a lot of territory (at least for my classic rock/blues rock needs). I emailed CM and asked if they had the overdrives in a single pedal. Unfortunately they don't. It would be extra-cool if they had a tuner built into it.
I have the tremelo version as well (every time I hear chorus it makes me start looking for parachute pants and it's all downhill form there).
It's a great unit -
-Compression is very transparent and works GREAT as a clean boost (and I dislike a lot of compressors - sold two old Dyna Comps over the years)
-Overdrives work great for me (wouldn't get you into metal territory but covers everything up to that point)
-Tremelo sounds better than any vintage Fender I ever owned and is more adjustable
-Analog delay is warm and organic (reminds me of my old Boss analog delays but more range and the tap tempo is very useful).
I guess you are at risk of losing everything at once, but it's such a well built unit, I'm not really too worried (you could always buy two!). One other added benfit - the effects are very quiet and don't really color your sound. I use the unit with my acoustics (K&K in the flatops and National magnetic on my reso) and it sounds excellent. All in all, for my tastes, this is a great value. Google the Guitar Player review for more.
