pH Test Strips 0-14: 200 Strips Universal Litmus Paper pH Test Strips for Liquid Testing & Water & Food and Soap Making, Get Highly Accurate Results in Seconds

I had read some negative reviews (1 stars) on this product and was a little concerned. However, I read the instructions and using some test equipment I verified they do work. I'm not suggesting they're 100% accurate but they are easy to use, seem a great deal for the price and from testing they seem to provide results very close to other test equipment I compared them to. I tried them on RO water, tap water etc. If there's one thing I think that might cause confusion for some is the color strip chart. These strips can give a very subtle color variance based on the water type tested but the issue here is simple... you're not testing for marginal variances... you're testing for water that is clearly acidic or alkaline which for me, makes these perfect and simple to use.

These were do easy and convenient to use. The colors matched the chart and were simple to see. Would purchase again.

If you can, these are a must need. I make salsa and thought I had a batch that I added too many tomatoes. It was peace of mind that the pH was fine and it not a mistake I thought I made. In the end it saved 7 pints of salsa being poured down the drain!

Too vague and lacking in precision.

I have tested these so far on tap water, ZeroWater and concentrated vinegar. From what info I can find online as to the ph levels of what these 3 things should be, these strips appear to be accurate. Much easier to accurately read than single color litmus paper and I can tell to within 0.5 difference of ph, which is good as I'm using these to test the ph of the water I'm using to water my carnivorous plants, which require a ph ideally between 4.5 and 5.5. I THINK a lot of the complaints that they "don't work" is because people are ordering the wrong type for their intended purpose. There are 2 types here: one with a range of 0-14 for all liquids, and another that's a more narrow range (I forget the exact numbers) for saliva and urine. MAKE SURE YOU ORDER THE CORRECT ONE FOR YOUR INTENDED PURPOSE!

I'm not sure these work. Unfiltered tap water, filtered tap water, and bottled water tested exactly the same and barely changed the color of the strip, if at all. I even tried another beverage, just to see if the color would change and...nothing.

The packaging is sturdy, and you get plenty of strips for the price. Definitely a great value and very handy to have around for home projects or experiments.
