I'm thinking about getting this since it's on sale and works with pro channel. How would you guys rate the quality of it compared to other commercial limiters?

I like it very much. I have used many others in the past but I find the CL to be outstanding. 

It works great. Get it.

Nice and transparent, without the artefacts heard in some lower quality brick wall limiters. Also, 64-bit signal path. I've tried a few but am 100% happy with Concrete Limiter.

It's terrific because: 1) Sounds great even when limiting heavily, 2) Made for Prochannel, 3) Very low latency which can't be said about many high quality limiters.

Get it.  Sounds great.  I use it on many different things.  Works wonders on bass and drums.

Worth every penny - and then some! If you have cash, it's a no brainer. I use it as a bus limiter and I am pretty much a full time addict to it!

I bought it yesterday - it's not bad, not bad at all ...better than I expected, actually.

I was intending to use it just to tame any rogue spikes in drums, but after messing around with it, I can see goosing it up a little more than I planned since it sounds pretty good - on both single tracks and busses.

Only tried it on drums so far, but I'll use it on other stuff as well.

I use it on tracks, busses and the master.
 
I've even used it successfully on a twelve string acoustic.

Good deal! Not one bad review. I have and use several good free limiters, but I've been wanting this one for awhile. Thanks to all.
