Rated 1 out of 5 by from Wildly inaccurate! Check expiry date before paying I can only assume that there's a quality control issue here as some people's reviews are very positive and say the results seem right. Southern Water say my supply is 250ppm or 17.7 degrees Clarke, My old 2-bottle kit was very consistent with this and itself over time. My water softener is functioning and the old kit gave a value of 12 Clarke. A test strip read 7-11 GPG or about 150 ppm. This Calmag test took 25 drops for the colour change from pink to blue. It was a clear change; impossible to miss. I agitated the bottle after every drop and have had years of experience! 25 drops means 500ppm, which is twice the level stated by the supply company!! I shall be contacting Calmag. I have just checked the expiry date; 07/20! It seems i should contact Toolstation, who sold it to me 2 days ago!!!

Rated 3 out of 5 by from Easy test for hard water Quick and easy to use product to test water hardness. Shame it has very short shelf life, less than a month.

Rated 5 out of 5 by from I came; I did; I went! I placed my online order; I successfully used my credit card to pay, got into my car, went to the outlet, queued in a manner respectful of social distancing, collected my order and left with a smile on my face!

Rated 4 out of 5 by from Good Seems to work about right. Have used with my tap water and water out of a Brita jug and seems to be about accurate though i have now way of being sure.
