For those like me, on a scale regularly, careful to take your time when you go up the scale. I find that there are two problems in this telescopic ladder. The first, when one goes up, the music system is not safe. We must ensure that the system is enclenché.Le second problem, when it is folded, elements descend quickly and the weight scale the bounces. Beware of fingers at the time ... Otherwise it remains obviously convenient for its small footprint ...
