It's a very satisfactory product for parents whose kids are keen to have a drum set at home.
I bought for my son for Christmas and he's very happy with it. I must say, it takes well heavy using... One has to figure out a bit all the settings, but eventually even if it doesn't seem in the beginning one can very well fine tune the sound level and the sounding to each pad.
We had an issue after a short while, the snare pad went out, didn't give any signal any more, but Thomann immediately replaced it. Since then on everything works fine.
Very important advice! If you go for it, check on a weekly/biweekly basis mtge screws and tighten them really hard each time. It can happen that during playing some parts get loose and go down. The same for the legs. I haven't yet done it, but I plan on glueing the little plastic legs on the aluminium bars, as sometimes during playing when one beats too heavily with the feat, can slip and upturn which might cause the all kit go down to one side. It happened 3 times to my son that ha caught the set and holding it until the rescue team arrived to adjust the plastic feet. It's not a big issue, I think with a bit of glue or silicon can be easily resolved.
So altogether it's a good set, great to learn, practice, amuse oneself. One has to pay attention that it's not the most stable so needs regular supervision that nothing moves out of place. Altogether we're satisfied with it and I'm glad that it can take hours of heavy beating daily and keeps working. I can say this after 6 months of intensive daily using.
