The electrostatic effect does not work so much, the telescopic handle is useful and well sneaks under the bed but not the cabinet.
So for the bottom bed I go at once to the vacuum cleaner and duster times, which also has a very short lifespan, not useless after a pass .. .
For the price it is theft.
So I bought a sub-brand at Aldi 2.99 20 dusters with short handle. There at least I regret not worth what it's worth.
