I really like this set. It was great fun to build it. Unfortunately 1 technic axle pin was delivered wrong, so I had to buy the correct one separately, but no big deal. Once complete, the set is stable, looks very nice to my opinion and it is working very soft and nice. No big resistance when turning the crank and you can watch the moon circle around earth within almost a month and the earth circle around the sun within 12 months. And as even the axis of the earth is built in, you can imagine how summer and winter develop during moving earth around the sun during a one year orbit. So a great tool to learn and understand as well as a nice little set to be built within a few hours of great fun of brick building. Good quality of the pieces, they fit good and there is no variations within each colour. The order process on joooooy was an easy experience and the set was delivered fast to Germany with good communication after having placed the order. Infos about order placement, payment, date of delivery with tracking number. Gave me a good feeling that the website is correct and professional and I am fully satisfied with the work of joooooy, as well as with the set from CADA. I will order again from joooooy.

Christmas gift, so can't give review on more the service and delivery. Made a mistake when filling the address in but just one mail sorted it out. Delivery was fast.
