weve been using one for a while and on standard domestics it is the best and you save loads of water, even a lot more that the aquadapters that we also use.
things i have noticed
on higher windows or windows above things like garages its hard to opperate, the aquadapter is much easier.
the week point of it are the small barbs that come out of the side, i dont yet know were to spares.
would i buy again, yes definatly
we have 18's which are used for most domestics, we wouldnt use anything other than the aquatap for these
and we have a couple of longer, 27 foot and 45 foot poles, the aquadapter is far better on these.
but yes for anyone interested we find it a great tool and its earnt its place, it saves quite a bit of water in most situations
