"Reduces the pressure of your shower way too much so much so that it's not worth showering with filter engaged. We have found the best way to use is to shower first and then engage the filter afterward to rinse down the shower screen. Definetly helps. But you only have to forget to rinse once and your screen is a state."
"I bought this item to use as described. It is a perfect fit and looks good in the shower. But in active mode the pressure and amount of water that comes out the shower head got reduced to hardly 1/3 and was not enough to wash the tiles and screen easily. The filter catridge needs to be replaced every 2 months as per the instruction and costs £20 or so. Its not worth the money you invest (£80) and is not economically viable. I have returned the product for a refund and going for a water softener instead."
