I was very curious and had to try the B20 18" cymbal for this money.
After opening the package, I couldn't help but notice that the cymbal is obviously much heavier on one side. Even with the naked eye, it is visible that it is thin on one side and thick on the other.
Of course, for this price one cannot expect a cymbal maker to devote much attention to shaping the cymbal, but if it is shaped mechanically with a machine, then the machine should be tuned a little :)
In shape and even sound, the cymbal resembles a Zildjian A Custom.
I don't know how durable it is because I just got it.
I think it will serve well for rehearsals with a rock band.
