Amazing product & Thanks to Scottish water

Easy to use and seems accurate for my needs
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.

Seems to work well
Very cheap quality but was to be expected given the price. I carn't vouch for it's accuracy however doesn't seem far off as it reads very low from my RO filter. It's easy to read and a useful tool to keep an eye on your RO filter to see when it needs changing

useful but overpriced
works well and its very useful. I gave 3 stars for thr price as I found same exact one with ph strips for 5.19 which is a big difference considering they are the same product.

I like the item.
I got one from other shop and it didn’t work. But this one works well. My tap water was 360. And water purified water was only 11.

Quality of uk tap water
Family have felt better after getting this - water quality in Uk is taken for granted- check your tap water and then use bottled water for tea/coffee-different taste - also any vegetables etc that require boiling use bottled water and the taste difference is really noticeable

I bought this because i didn't get a TDS meter with my zero pitcher. I thought it wasn't working when i first tried it because it said my filtered water has 0, and it had been almost 3 months of using that particular filter, but then i tested it on my tap water and it was around 150 so it does work! My filter is just lasting longer than I thought it would lol. Really good price too, I'm happy I got this one.

The pen works great the only thing I would wish they add to it is a EC chart break down. You will have to look that up and print it out. Besides that it's a great value for the price you pay. The LCD screen is easily legible. The battery life is also great.
