I was a bit sceptical about these, thinking that maybe they are overrated and overpriced.
I still think they are a bit overpriced, but definitely not overrated. They offer great control and dampening of sustain for your cymbals.
Very nice and very flexible, you can completely change the settings in-between pieces in a gig.
And also the 2 different sizes they offer do have different effects. I am very happy with the product but I think the price could be lower.
On the other hand, they also come with this fancy container, which may be the reason for the high price!
