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.

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

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.

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.

These are super cheap and the paper is so dark, it's hard to tell what color you get when you use them. The color also drips off (watch for staining!) and fades really quickly. The included color reference chart really doesn't help at all. The strips might work better if the paper was white, since the chart is on a white background. I found these utterly useless and bought some plastic strips in a canister instead.

Easy to use. From left to right. I expected more color difference between Saliva & Chlorinated Tap water? Salt water, Dill pickle juice & Ice tea all look the same pH. Not sure if I did testing correctly. Additionally, center photo is Distilled water, far right photo is tap water that sat in open containers for 6 hours.

I was so excited to see these things. I used to use these exact same ones in the laboratory. They work great. Would definitely recommend. You only need to rip a tiny piece off, thats how we did it in the lab, it will last forever
