This pedal is made to be used in stereo. It's a dimension effect designed to create a feeling of spaciousness, and obviously this will come across much more convincingly with two sound sources than one. In mono it just sounds like a subdued, airy 'Police-type" chorus. Nice, but in no way worth the US$150+ asking price it commands on the used market these days. In stereo it sounds quite different - better - it creates the impression that your playing environment has expanded (say from a room to a plain), adds a chorusy/dreamy touch, but sounds nothing like a reverb. Each preset drops the dry signal further back in the mix, increasing the feeling of spaciousness (i.e like your speakers are dropping back from you a few dozen meters, but (thankfully), there's no volume drop). If you own one and have never used it in stereo you have not heard this unit performing to its full potential.
If you had more control over the effect it'd have given it a 10.
Reliability/Durability:
Typical Boss quality.
Ease of Use:
There are 4 buttons to cycle through 4 stages of effect depth. Toddler toy ease of use. This is a compact "sequel" to Roland's famous Dimension D rack unit.

Overall Rating:
The Dimension C forms a major component of my "sound". It's very complimentary to ambient/shoegazer music. I think it's somewhat overpriced for what it is, but the demand is high because there really isn't anything else like it in the market (besides the Rack Dimension D on which it's based, but that unit is many times more expensive again). Although I've never played either, word on the street is that the Boss DC-3 Digital Dimension or the Dimension D model on the CE-20 don't come close to matching the warm sound of the analogue Dimension C. If you can find one under $150 you're doing well.
