Anyone with experience of the Hozelock system?

I have an outside tap at the back of the house and 3 half baskets at the
front. To avoid a run of the larger (13mm?) pipe I would like to do
most of the run in the narrower pipe which, although it is black, I
could hide more easily against the join between the white soffit and the
brick wall.

I am havig problems locating the appropriate kits in garden centres as
apparently Hozelock are revising their product range and the garden
centres only have what is left of the old range. Timing is important as
this is meant to be a Christmas present from my daughter.

Any thoughts
