Does anyone use a Kenwood for kneading dough?

I've just bought a Kenwood Prospero machine which is the compact model of 
the Chef. Using it for kneading dough it does seem to be straining and 
though the book says knead on minimum to mix ingredients, then a further 1

minute on minimum, then knead for 4 minutes on speed 2 "until smooth and 
elastic". After that time it's not as smooth and elastic as I'd like but
the 
machine seems to be getting a bit warm. I was wondering how long a batch
of 
dough took with the full size machine? I used a breadmaker prior to this
and 
finished the loaf by hand. That certainly did produce a very smooth and 
silky ball of dough though I think it kneaded for 20 minutes or so.

Apart from that I'm very happy with the machine for pastry, cakes, scones 
etc and can recommend it for singles/couples.
