### ⭐⭐⭐⭐⭐ They work well

They work well

### ⭐⭐⭐⭐⭐ Great for rapid testing of spa or pool pH levels
*by A***J on 2 September 2023*

I bought these as my kit had run out of tablets. Originally I ordered the 'non' rapid tablets which aren't great. These rapid ones as soon as you put them in the test tube and shake for 1-5 seconds have dissolved and changed colour to read PH. Note- they are only refill tablets no kit included you will need that separately.
