This board uses Outemu Blue switches which are known to be some of the loudest switches around, even more so than the Cherry Blue. They are also "scratchy", in that they have a little bit of odd feel when depressing the keys.
Other than that, the Outemu switches aren't too bad for a Cherry clone. Many prefer them over the Kalith switches. Quality control won't match true Cherry keyboards however. And you won't want to use this keyboard around other people, since they have a very sharp, CLICKY sound.
