Great fun ... 1 4

Arrive on time and some large packaging relative to the product.
Inevitably, cardboard arrives home deformed. To believe that the Post Office, they play football with prior to delivery ...
Indeed, a lot of fun playing with this marvel of technology.
No adjustment to do more than correct stability!
Being able to use it in very small volume of a small room is a very big advantage, but it also gives quickly the urge to go out with. So it's probably just a toy through before taking the top model to go faster and further!

By cons, side autonomy, what frustration! Hardly one begins to really master the unit down to the floor. Anyway, I knew before buying, it is also part of the game ... But when the most powerful batteries?

Be careful though, the product is not as strong as suggested by the information given by various users. Do not leave in very young hands and handle with care. A good point, the spare parts are available at good prices.
