Commetns spassk-dalniy.gallerynn.ru :
Fast shipping and delivery ,I was satisfied and recommended this seller, excellent condition with good package.

No English instructions, only Chinese.

Looks as described. Not tested yet.

The instructions are very poor. There were only in chinese, but this is not the main problem. The first 20 pictures of the instructions are quite acceptable. But in the last 8 pictures you cannot understand anything. I managed to finish it from the pictures of the website, but I am a mature man. A child 13 years old cannot fix it alone. The movement of the model is not very good, but this is not the main problem. Also there are different sizes of screws, but nowhere shows at the instructions which one you use every time. You have to guess it. Finally in my parcel there was one nut less. It is not so difficuilt to put some extra screws and nuts inside the parcel.

Quality of shit, the tree is poorly processed, it turned out a pain, i do not recommend = (

good

Good quality and easy to build. Instructions are included in Chinese but with good pictures, so we didn't need instructions in an other language. It was a lot of fun to build the toy with my 5 year old son and a great way to not only explain but to show, what hydraulic means

Satisfied. Good fast
