Lime scale removing Post Filter (HS1 Gold)

Products are at best average and the price being charged for a Push connector is almost £26.00 however purchasing same product from another supplier on-line was only £4.50 including delivery. Overall extremely disappointed

I was a bit disappointed in the lack of instructions where to put this filter next to the main 3 year filter. The previous filter had a more detailed label and also had a direction of flow indicated which was not on the HS1 Gold. I had to ring up to get the required information. It would have been nice if a diagram showing how the 2 filters should be connected was supplied.
