Blade has come loose with use,
This review is from: Kenwood Wizard HB615 2-Speed Pro Hand Blender, 400 Watt (Kitchen & Home)
Blends well and the beaker is useful - but twisting / unscrewing the blade from the motor unit (in order to clean it) has led to the blade coming loose, which is annoying. A friend has a different model of hand blender which has a push button to release the lower half and that seems a much less laborious and more robust way of achieving the same thing.
