Very disappointing Scale

Already a user of a telescopic ladder, I find this chilling pattern: very "flexible", even if not fully extended, the scale slides on a smooth floor (no slip tip). It folds easily, but folding, even "safe" is very violent. At times, some fallback systems are blocked and the scale is very difficult to fold. Finally, technical aberration for the laying of the stabilizer bar (problem already mentioned by another user) can be prevent slips but that is impossible to mount "one wonders what use are metal rods riveted to the slot in each foot because it would be able to ask for sawing the bar. " There is no mention of this bar on record: neither images nor in explanations. So I do not recommend it at all this I return!
