The negative points:
The base is fixed with 4 screws with hexagon socket on the big circle. After 3 days of play, one of the 4 screws left ... Not so good in terms of quality control ... I think it was pretty much screwed. Luckily we found the front screw my daughter. An Allen key blow on the screws and also found a small reserrage in good standing of the other 3 per security.
