### ⭐⭐⭐⭐ Seems to work well

### ⭐⭐⭐⭐⭐ Easy to use and seems accurate for my needs
*by S***5 on 26 May 2025*

Easy to use and good value for money. As advised the readings took a few moments to settle, but all my taps' readings fell into the upper part of the high hardness band. Way off the maximum contaminant level and I know I do live in a hard water area. Had been concerned about the age of my pipes.
