The delivery went well! The connecting elements of the drum frame are very weak! The structure creaks and creaks. This can be fixed if you are skilled! The thing stops with an extra stiffening element! I bought the set for my son, it will be enough for him for a long time. I do not recommend it for advanced, concert musicians, although the sound is quite tolerable! The "learner" songs are quite primitive, especially the harmonics. In the end, it was a good choice in terms of price-performance ratio.
