## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy to tell hardness
*by P***S on 22 May 2020*

I've used testing strips before and found them pretty vague as there isn't much difference in colour between hard and soft. This kit has a strong change of colour from pink to blue, and is very sudden. For instance there was only 1 drop added after 20 to make the colour change, so I could tell the hardness was 400 to 420 ppm and the water softener wasn't working. After doing a resin clean the colour changed after just 1 drop so water fully softened.The older strip test however went from muddy brown (couldn't really match colour so didn't know hardness) to green so did confirm that water was now soft. The strip test wouldn't have been useful for setting the salt level on a dishwasher or coffee machine accurately, while this testing kit would give a much more accurate idea of water hardness.

### ⭐⭐⭐⭐ Useful

### ⭐⭐⭐⭐⭐ Accurate, cheap, reliable.
*by P***Y on 19 April 2019*

Use this for hot tub in a hard water area. Very accurate and easy to use. A bottle lasts for years. This is my second bottle in seven years.
