I'm an established sound designer and performer in the ambient music genre, and it was years I was not getting an "instrument" like Collider. Yes, there are better delays and reverb out there, of course they are much more expensive and super cool, but... Collider mix them together in a perfect way.
High end algorhithms (many, unlike several other combo pedals) that make sense and each have a specific personality, interact in such a musical way that makes me say "so well balanced!!". Not quite often I found the same stunning quality in a combo pedal.
At the cost of one good pedal you get two, and "perfectly playable". Yes, I simply can tweak Collider while making loops and phrases with my guitar and it's instant ambient music, instant creativity, moving all of the many features this pedal offers (read the manual and you'll know you can easily tweak live a lot of parameter). I can imagine what will be when I'll add a MIDI controller to my pedalboard, since Collider has full MIDI features...
This is not only a pedal, this is an instrument for creativity. Nice is the Neuro app too, that is very easy to setup and offers in-depth program features to create whatever preset one can imagine (but you surely use the pedal itself if you don't have a pc when you're playing live out there in the world...).
The only cons I found is that it cannot "trail" while switching from an algorhitm to another, but I undestand it's not the common use one can make of it (it can only trail while switching off delay or reverb).
