That no assembly instructions here was was already mentioned in another review. I had even assembled no drums, so it was because of the large number of parts already a puzzle. I recommend the establishment to watch the image in Amazon enlarged as it the items are already clearly visible, which should help.
The instrument does not sound like Spielzezug, but quite good. From the quality of the parts I was pleasantly surprised.
The only thing missing to complete the drums would be a hi-hat, but you can expect at the price not well. The parts in the photo were definitely all there.
For size: our son is 5 years, for him, the Drum Set is perfect. Our 8-year-old daughter has already tried it. Everything is adjustable in height, it fits well for them.
