Very poor product!

I bought this Go-kart to transport some of my gear on the road, but when this arrives i spent almost 1 hour trying understand how it opens, and it's not user friendly at all.

To open it, you need to push a steel cable so hard that hurt's a lot, to get ready to use, it takes a lot of time, doesn't make any sense.

The user manual probably isn't updated so i can't understand how to lock the wheels, says there to use some screws, but doesn't have any spot to screw it.

In general i'm very disappointing with this product
