The glass blender jug is fine - pretty heavy when it’s full but nothing you can’t lift with two hands.
Connecting bowl to base is fine, same mechanism as my previous Kenwood, except you add a spindle that goes up the centre of the processor bowl. Comes with a load of attachments.
The little glass spice grinder bit is very handy.
I ummed and aahed before buying, worrying Kenwood quality might have dropped off like nearly everything else seems to have, but I’ve had it about 3 years and it’s pretty solid.
