Very good sound / complete set for the price, can really compete with Zildjian A Custom or Sabian AAX for a much more accessible price!
I've used them to play Rock and Metal, and I'm not really disappointed!
The 17'' and 19'' crashes respond to the slightest touch and can also provide plenty of volume without needing to "hammer like a brute" to get it out.
The 15" hi-hat is also very nice, with a precise, well-defined sound and a nice "chick".
I was just expecting a little more volume from the 22" ride, but the contrast between the body and the bell is really top-notch, so overall I highly recommend this cymbal set.
Thanks again to the Thomann team here for their good advices, because I might not have bought it otherwise but so far I really don't regret this purchase!
