I ended up buying one, and I drove it for an entire year. The wheels of the stage came crashing down with a spectacular collapse as they reached the bottom of the pit. Make an opening through one of the side walls. The top is of very high quality. Made the decision to switch to a new one. Bought. The wall thickness of the bottom section is 1 mm, and the plastic itself is quite brittle. The previous version was more substantial and cushier. As a direct consequence of this, it exploded and shattered into a million pieces. About 6 kg of weight were driven. In conclusion, the quality as it stands is not satisfactory. You shouldn't put too much stock in that. view photograph
