I tried this out but it doesn't appeal to me much.
There's a huge GR meter in the middle of the GUI but it only applies to the amount reduced by softclipping. If you were using this for mastering you would probably avoid the softclipping, so most users are just going to find that GR meter a waste of space. Also the needle on the thing is slower than a snail so it's pretty useless even if you go for the softclipping.
There's no bypass on the GUI. The speed/resolution dial doesn't seem to work properly when you bypass via the daw. So that's another irritation.
The transient process sounds decent, it has two hipass filters that can be optionally applied, haven't seen this before. However, it doesn't really do anything special and can't give extreme sounds. If I wanted a quick light transient shaper I would probably go to Bittersweet by Flux.
