I've used it in four batches so far. All fermented in the mid 60s. It's very clean at these temperatures. It does seem to mute hop expression just a touch, but a small recipe adjustment could take care of that. It ferments fast, but likes to hang out on top of the beer afterwards unless you cold crash. It definitely clears much faster than US05, especially if you apply cooling. I don't have my notes in front of me, but IIRC attenuation was close to 80%.
