Works Accurately
Arrived on time, everything as expected. Works accurately, tested with various amounts of alkaline drops in highly filtered water.

Understandable and Does as described
I've used other water testers to make sure this was accurate and it seems to be the case. I tested this on distilled water, my city water, my RO water, and Spring water I purchased as well. Seems to be OK!

Works Well!
Been using the same one bottle for a couple of years now. It's an excellent product, but lost a star because the color comparison card is so small (about the size of a business card) making comparison more tricky than it needs to be.

Worked like a charm!!
This liquid actually did what it was supposed to. I had 8 brands of drinking water that are popular on the market today. The water you think is the best, is not. Do the test for yourself, it actually shows you the level of PH- balance in the water we drink. Then, you decide from there if you will continue to drink the water that is YELLOW or not??? I would put my photos up, but truth hurts and do not want companies contacting me.

Get what you pay for🙂
Quality product, accurate description, I have made multiple purchases, beware of a look-alike at a lower price, I purchased it one time and it was completely deceptive, less than half the size, Amazon took care of it immediately, this product is the real deal, easiest to use compared to most other test liquids, most accurate colors scale, good value

this bottle of liquid works
I bought this to test my tap water. And was I shocked to discover the tap water turned brilliant purple. Far exceeding basic alkalinity. I now drink gallons of my local tap water. I no longer carry those heavy cases of dead water on my shoulder up steps to get inside my home anymore. what a relief.

Hard to read
I just tested my Millenium water filtration sticks. Top right is tap water, top left is older filter, bottom is newer. It’s really hard to tell the difference in person or match to colors on the bottle, photo shows a little more variance. Bottom one seems to have the 9.0 ph. I guess I’ll keep it and try to read the results in photos! I put a piece of clear tape over the bottle colors to keep them from bleeding in case I got them wet
