I use it for 2 weeks and I am very satisfied. Again, with K it takes a bit of time to master the full range of sounds of cymbals.
As this cymbal is very thin, it is very reactive and has an amazing projection. It has a very dull tone and as the name implies very very dark, can be a bit more than traditional K. I played for a long time on Sabian HH Thin and K Custom harmonics has a longer warm but less "brilliant".

At value for money, it's true that this kind of cymbal is expensive and performance is in terms of price but I find them too expensive compared to what are Istanbul and Bosphorus cymbals with their equal in quality.
