I normally avoid gadgets but this one sounded promising. It probably works brilliantly if you have the tap that it was designed for - but it doesn't fit on any of our taps, bath, sink or basin. Managed to squeeze it onto a basin tap but because of its solid colour you can't see whether the tap head is in contact with the liquid. A clear plastic bag and a clothes peg works a lot better and you can see where the liquid is and whether it is fizzing and clearing the limescale. Sadly a complete waste of money.

Just too small and tight for my bath taps. I ended up trying to force and getting a face full of cleaning solution. Works on my sink taps but rating given as I need for my bath.

I bought this on impulse, to help descale our very-limescaled taps. Maybe I wasn’t using the best descaler solution, but for all the fiddling about, it only marginally improved. I then tried the sonic scrubber which didn’t help either. I then realised that the noddles screw off. So I popped them in descaler solution and that did the job.

Good quality. Did the trick. Will use it again.

Combined this with the limey solution and all the built up limescale came off and even better there were n strong chemical spells.
