Electronic Scale Inhibitor is rated 4.3 out of 5 by 8.
Rated 5 out of 5 by from Scale gone This replaced an old one that had stopped working after 20 years. Could see results after 4 days, excellent.

Rated 4 out of 5 by from Works well This replaced one that packed up after 20 years! Bet this will not last as long. It was easy to fit apart from the mains plug (under cupboards) but would have preferred the transformer to be on a plug not in the unit, unable, due to warranty, to cut the mains plug off it made a straight forward job three times longer. Could tell after a few days that it was working as the other one did. The shower pump got quieter so hoping for good things as time goes on. Good buy at the price.

Rated 1 out of 5 by from Certainly inhibits something Currently unable to effectively review this item. It is defective and am awaiting a replacement. I spent 30 minutes installing it only to find it inoperable. Another 30 minutes removing it so.......

Rated 5 out of 5 by from Fantastic product Fitted it 2 weeks ago we can see the limescale disappearing from around the taps already and the diverter valve on the boiler has stopped sticking mid position. This is the second time I have fitted one of these type of units Highly recommended product

Rated 5 out of 5 by from Works very well. Works well, easy to install, (apart from having to lay on my back half in annd half out of a kitchen cupboard whilst winding all the aerial leads around the pipes, but that just happens to be where mine needed to go.) Seems robust. Very happy with it.

Rated 5 out of 5 by from Works Well worth the money, had one in my last home and made a massive difference, at the time I brought this from Toolstation, they where £20 cheaper than anywhere else! Love Toolstation.

Rated 4 out of 5 by from Lets see how effective agter time I'm always sceptical about these, however I researched and was convinced by (non manufacturer) explanations so have given it a go so can't comment on effectiveness yet. Looks good fitted but instructions not great. No guidance on minimum coil turns (ie how close to the intended pipework do you have to be in order to ensure enough aerial leads left for colis) or what direction to wind them (both coils same direction? opposite direction?) or how far apart the coils should be. I followed the very basic diagram and hoped for the best. Also found trying to secure ends of coils with the provided cable ties almost ineffective ( I worked with relays, coils and cables for 20 years) and securing with tape to ensure no unwrapping is advisable.
