The packaging was a little light, but the essentials are there: Special hard floor brush. Both say: the revolution. Finished the brush provided with the Dyson DC29 vacuum makes every two seconds (with the risk of scratching on the floor ...), and finished the cramps to the index in force continuously pull the trigger. With this brush, it keeps the suction efficiency, even against the walls, and it no longer sucker.
No regrets for this vital final purchase, either on the floor or on the floor.
