Easy to use and store due to clever design that incorporates the Limey with the bottle. Used overnight on our kitchen tap and worked a treat.

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.
