For testing radiator pH I needed a tweezer to dip. However, worked well and saved a lot of money for a suggested radiator flushing (previously done) that was not needed

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.

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.

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.

The package arrived on time. They are easy to use, and the pH values are accurate based on the colors on the table after testing. Very easy to read, the size is small, but it is perfect for its purpose. Good quality. I used them to check my homemade skin care cream and the acidity of my homemade apple vinegar; the accuracy was perfect. I will purchase again.

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.

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.

These universal pH indicator papers are easy to use and come in a handy matchbook-style pack, which makes them super convenient for quick testing while I’m making soap. The color chart is clear, and the strips seem accurate — I’ve gotten the right color range every time so far, and it matched the pH I needed perfectly. The reason for three stars is that the paper itself is very thin and could definitely be made thicker for easier handling. It tends to feel a bit flimsy when dipping into liquids. However, for the price, they do exactly what they’re supposed to and get the job done without any major issues.

A described. Good value.

bought for my boy, he likes testing everything with it

they work! however if you're after any kind of accuracy do yourself a favor and get a digital PH meter. don't learn the hard way like I did.

I bought the wrong strips. That work for sure. But there not accurate enough for me

Bon prix.
