4.5 Great looking, great idea, useless when batteried up...... joepublic2 | 30/11/2011 | See all joepublic2's reviews (1) We bought 2 of these as Xmas gifts and decided to put the batteries in well beforehand - "just checking". Although the motor came on, there was no suction whatsoever. And that was the same for both of them. Lots of breeze out the vents, no suction up the tube. Real disappointment. Such a pity because we loved the idea of them.
