The perfect telescopic ladder

+ 4m extension length, pushed together 105x55 cm
+ Stable, stable (some are as much shakier, even if they are longer))
+ TÜV-GS mark
+ Can be well wearing, despite 14kg (simply lift on the shoulder - final stage, rubber grip serves as Posterung)
+ Retraction with foot operation (so you can outside the circuit for retraction can hold with both hands and together drive carefully)

Only comment / suggestion from me is that the velcro is still in the extended state somewhere could moor, it occurs otherwise it always around.

Otherwise, clear recommendation and stay away from the cheap telescopic ladders
