They work well and come in a nice easy to use roll incased in a plastic holder. They won't break and become unusable like a cheaply made ph pen . The liquid indicator drops also work well to test ph. Many uses such as gardening and testing ph liquid products and water.

Our puppy is having problems with chronic UTIs so we check her PH weekly. She has a lot of allergies and is very sensitive to typical dog food ingredients. Having a quick litmus test has made checking her health easy. Our goal is to keep her PH at 5.5 to 7 the easy color chart on the dial helps us know if we need to add some apple cider vinegar to her food. These easy strips make checking a breeze.

They came on time and each spool was in a cardboard box and then both boxes were placed inside of a sturdy plastic zip lock bag. The spool of ph paper is wrapped inside of the case with some sort of aluminum covered type of paper. I presume this is to protect the ph paper until you receive it and are ready to use it. To open the case and unwrap the ph paper I just slightly twisted and pulled apart the two pieces of the plastic casing to reveal and remove the wrapped spool of ph test paper then I reinserted the unwrapped ph test paper into the plastic case with the end of the ph test paper coming through the little slot on the case which then enables you to pull the desired length of ph test paper you require then you use the little serrated toothed edge on the case to help tear the piece of pH test paper off to use for testing. I performed a couple quick ph test using this product as you can see in the picture I provided it shows two longer yellowish strips one of those was used to test tap water and the other was used in spring water, the orangish colored test result strip was sweetened peach iced tea and the short little yellow test strip was saliva they all showed to be in the proper ph according to what google said they should be so I think it is safe to say they work! I will be using them when I make homemade skin care products as some of these items need to have their ph adjusted so they are not so harsh on the skin. It says each spool is 5 meters long I am actually surprised they did not appear to be that long and I have not measured them yet! But if they are indeed 5 meters each and if you used strips that are approximately an inch long you could get close to 196 ph test strips per spool! Which I think is an amazing deal for the price however I have not comparison shopped to be sure of this. I bought the 2 spool package since I was not sure of the quality and price and I was short on funds at the time. In the future I would probably order a larger package after I researched and determine how long the ph test strip paper is good for in storage and if it is actually the best deal. However these two spools may last me a lifetime with the amount of test I can perform depending on how easily it is to adjust the formulas I make... idk time will tell! I only make products for myself so I don't need these very often and they are only needed for certain formulas it all depends on the recipe and products that go into them if I need to check the ph levels and adjust them. Having the ph test paper now enables me to make formulas I have not been able to make and try in the past! So this is exciting! Knowing me I will probably also be testing all of the formulas I make even the ones that have claimed do not need to be tested and adjusted just to be sure they are correct! Trust no one and nothing! ;)

I can't really say anything about the accuracy of the pH strip because i would need another method to test pH and verify the strip. However, it seems to work well and it's convenient and easy. I've been testing fermented garlic in honey. Honey has a low pH and that's what i've been getting from the strip.

I bought this without looking at the 1-star reviews. The reviews I read and the video I watched lead me to believe it worked. I just had my water tested professionally and was interested in testing it myself, along with my filtered water, and other items I have. Don’t bother. It is nothing more than an orange dyed piece of paper that does not change color. I tried my kitchen faucet which I knew the reading, color did not change, and I knew it was not correct. Tried it on my expensive filtered water, which is Alkaline, same color. I then even tried it on my tongue like the person in the video, same color. I then sprayed a part with Windex, that did change color! But if you are testing the water, it did not change at all nor did it when I put it on my tongue. The pack was new and sealed properly so can’t even say it was an old batch. Would not buy, save your money. PS, it did stain my counter orange, that tells me all I need to know. Each strip I put down they all stained the counter the same orange tone.

Every time I use this to test ph of kombucha I get the same reading no matter what. I started comparing with a more expensive strip and the results are always different, they never match. If you need accuracy this isn’t the product for you, it’s in the same approximate range, but NOT exact

These will tell you if something is acidic or basic, but they aren't a super precise tool. Great for their intended purpose though.

These work very well. In the photo you see the results of a control test, on the left the results of a vinegar (acid) solution and on the right a baking soda (alkaline) solution. The colour of the strips clearly indicates accurate pH measurement against the provided reference. I used these for a soil test to determine adding lime to tomatoe potting mix. They displayed a neutral result tested with the soil which looked the same colour as the testing paper but just wet. I think this result is why some people think it doesn't work. Would recommend over the cheaper options found on amazon. Shipped quickly, accurately and in good condition. Will buy again.

Las estoy utilizando para saber el ph cada dia de la orina de un perro con piedras de estruvita, me va muy bien para poderlo conocer para hacer valoracion a su vez del funcionamiento del tratamiento. Facil y rapido de ver.
