I purchased these for my son's science fair project. They worked really well!

I bought these to test the Ph of skincare products, because my skin can get alllll angry if I'm not careful. These work almost instantly, it's a nice big test strip so easy to read, soyou're not squinting at the color chart, and they're a really good deal. I will probably not use even half of these before they expire, but I will buy them again when that happens.

Typical pH paper. Don't use these to read the pH of a pool as it will not work. The pool chlorine can chemically react with the pH indicator dyes on the paper and will not change color.

Ph value for most part is accurate but functionality is a lil iffy the rooms light or sunlight kinda changes it to where it’s hard to tell it says keep outta light which I get but kinda hard to tell the ph color then.

I love these test strips. I also purchased a digital ph tester and actually prefer these over the digital tester. Dip them in, watch the color change, easy peasy lemon squeezy. UNLIKE THE DIGITAL TESTER. Calibrate, if the instructions are clear enough to understand, then make sure you use the correct solution, then make sure the sponge at the top of the cap stays MOIST ALWAYS. Can’t dry out, so if you’re not using the digital ph meter weekly, you have to REMEMBER to moisten the sponge, yahhh like that’s going to happen!!! Get the strips MAKE YOUR LIFE EASIER

They do NOT WORK. I bought these to test my semi hydro nutrient solution once nutrients (silica, cal/mag, foliage focus) are mixed with my Colorado tap water and it doesn’t matter if I put straight tap, individual nutrients, or the whole solution- the paper doesn’t change AT ALL. Idk if they’re old or what, but they suck.

Bought these to test the ph of my fish tanks before adding triop eggs and they worked perfectly and were very easy to read! Triops are extremely sensitive to ph and they hatched within 24 hours so id say these are very accurate strips.

This item is of the most help when making Homemade Vinegar. I was sure if I had completed the fermenting progress until I tested it with these strips. They are also handy for testing the PH Levels in my fish ponds and aquariums making it versatile in uses. The Color change gives you a fast answer to what the levels are. Colors also make it easy to read.

These strips are convenient and work great. I recommend storing them in a plastic bag so humidity doesn't degrade them.

The strips are pre-cut into stacks within the booklets that make them easy to use. I calibrated them with some substances I knew the pH of (baking soda water, distilled water, and lemon juice and found them accurate.

Really nice product. Strips tear out easily and very easy to read. I had three different water sources I wanted to check and you can see by the pic, the differences (which I completely expected) showed very clearly (would be easier to see if I put it on a white background for u to see) Only suggestion is to have the comparative color guide on the outside of the cover and not inside. I don't want to contaminate the unused strips accidently even though there is a minor chance of it happening. The white page directly beneath the strips (which covers the unused strips) is also nice, but would be better on the side to more easily compare with the color chart, but overall a great product.

This pH strip test is highly effective and comes highly recommended. It is straightforward to interpret the results, which are available within a few seconds.

Pretty accurate and so many strips. This is perfect when you need to do a bunch of testing till you get ur mix right.
