I have purchased the Thomann set including Zultan Rock Beat cymbals, etc. What can I say? It is so beautiful! It is so big! With four toms one can play in any style, and miss nothing. The snare drum has a big, fat sound and the toms and bass drum also sound great. The quality is excellent. I am an incurable perfectionist and always look at every detail looking for a scratch of fabrication error, but found nothing. It is a jewel! The skins made by Remo have great quality and all drums tune well. The wood is thick, sturdy and has a full sound.
The only drawback: it is so big that I couldn't find a drum carpet big enough for the whole drum set! It occupies more than 4 m2! So, you better have a big room for it! I will have to buy a normal (big) carpet in a furniture shop.
