Rated 5 out of 5 by from Good Value For Money It's a little difficult to rate performance on something like this but it does represent good value. It was easy enough to add to the system. I applied it with a small funnel through the top plug of the bathroom towel rail with no problems. I would suggest you have a rag handy though as there is bound to be a tiny bit of spillage at some point!

Rated 4 out of 5 by from Good product at the right pric Bought this as an impulse buy whilst in the shop. I had looked on line with other company's and was put off by the high delivery costs. Seems to be as good as any other...so will wait and see what happens this winter.
