A nice gentle compressor that's really easy to use. My only real issue with it is that adding makeup gain causes the meter to bounce around above 0dB, so it's a bit difficult to tell how much gain reduction is actually going on. The interface is clean, easy to read and pretty self-explanatory, so you can get started pretty much straight away. I also recommend the developer's other plugins, especially their RLC79 compressor.
