Construcit is good, but...
1. The bolts on the steering wheels bended after 2 or 3 uses with less then 70kg load. I had to fix it on my own.
2. Wheels got flattened after just staying in trailer on "normal weather", not too sunny, not to cold.
3. Sterring side is very winey.
Total:
It's maybe good for 100€, for someone, but if I knew this was this bad, I would buy more expensive one with better quality.
