Functionally accurate considering the range
One should understand what this is, it's purpose, and limitations before buying it. What you are specifically using it for makes a big difference on whether you will find it useful or problematic. [Kinda like don't buy a hammer when you actually need a saw.] Litmus paper comes in a variety of ranges and sensitivities, and you either have something with a wide range or something extremely detailed, but not both.This one uses a very broad scale litmus, running the entire range from 1-14. As such, if you need a high degree of detail, like to be able to differentiate between 7.8 and 8.0, this is not going to give you that level of detail and be worthless. But those detailed litmus papers also aren't going to give you that range that this one does either, and are probably limited to a range of 6.5-9.0 at most, also making it useless outside that range. There are no decimal values in this litmus reading and you'll not notice any significant difference between 4.0 and 4.5 for example.Also be aware that like all litmus, the texture of the paper is different than it is on the scale, thus giving it a slightly different look. What you're looking for here is pigment value, not an exact match in look. The same thing holds true in pH testing methods that use a liquid like phenolphalein or pH indicator such that you'd find in a swimming pool test kit.Essentially, this litmus would be completely inappropriate to use where a range of <1.0 where the result is mission critical. Again, it's designed for wide range, not high detail. But it makes it very appropriate to use in processes like cold or hot process soap making to know that you've got a finished product within an acceptable pH range like between 9-10, but where wrong calculations could leave you with highly alkaline soap. It's also completely inappropriate to use this to test human saliva or other bodily fluids that generally have a healthy range of about a half to a full point. This is close to that normal range that the litmus is calibrated to, it won't change much if at all, and it won't give you the detail that most people are looking for.This litmus will develop it's finished color within a second or two, making it a very fast paper. However, it should be noted for those not familiar with such testing, that this can only test a wet product, not a dry one. So for instance if testing a bar of soap, wet the soap with pH neutral water like distilled water, then wet the litmus paper with the resulting liquid/lather.I haven't seen how long the litmus will show a valid test, but you can make an accurate determination within a few seconds, and I've seen no change in the color, even 5 minutes out. Do NOT reuse litmus paper under any circumstance, though if in a pinch, using the other end that wasn't previously used might be acceptable.

What I learned about household cleaners
Accurate, at least as far as I can tell, water tests at 7pH which is what it should be. Lemon juice tested at 4 which is low but every lemon will be different. My only complaint is the alkaline colors don't closely match the colors printed inside the cover. For example, testing one cleaner the main part of the strip is similar to 10 but the darkest part of the strip is close to 11 so which is it? But I remember the strips we used in college having the same problem so I won't hold it against these. You get 2 booklets of litmus strips in a small plastic ziplock bag, probably a lifetime supply for me. I use them to test the pH of various household cleaners to help me make homemade cleaning solutions and what I discovered is most are alkaline, even citric degreaser. Of course then you go around testing anything and everything from spit, coffee, OJ, milk, etc.Here are some of my results:Acids• Barkeeper's Friend, 2• Citric acid + water, 1TB/Cup, 2• Kaboom, 3• Star San, 5Neutral• Pine SolAlkaline• HDX Citrus Degreaser, 10 (generic version of Zep)• Mr Clean, 10• Scrubbing bubbles, 10-11• Windex, 11• Oxyclean, 12Hot sauce, 4Lemon juice, 4

Definitely easy to use and takes up no space in luggage.
Color legend is in the kit which includes 2 kits each having its own color guide.Would prefer smaller increments of pH levels, such as 8.5 or 8.25, but not sure this exists at all with this kind of paper testor. This is a good starter kit, but no advantages, other than cost, over other kits being sold. The fact that similar products are sold in the most common local drug stores for 3 to 4 times the cost, just shows how much the drug stores are taking profit from just a small packet of papers...really not worth buying anyplace other than on line...where profit margins are reasonable instead of excessive. Drug stores are turning into castle structures due to selling everything more expensive than on line and making so much profit. So thank you Sonkir company for not gouging customers and charging a reasonable fee, unlike the local stores.

Accurate results saved my plants!
I started a garden and was curious about my soil and water PH.I set up a small experiment to first see if these test strips were accurate. I tested baking soda and got the correct basic result. I tested pickling juice (all I had) and got a correct acid result.I than tested 8 different household liquids for 20 to 30 seconds and everything came back within range. The strips I received have been accurate.Additionally, I learned my soil was within range however, my water is extremely basic and probably the cause of my yellow plants. I changed my water source and my plants are already greener.I'm very happy I took this approach and invested in this product!!

Read for reason of the 3 stars
Honestly I am not sure if it should be a 1 star or 5 star review.First off I bought these because one of my favorite internet canners uses them and I trust her. My issue is the date stamped on them. 2-22-21. They came with no literature explaining if that is a use by or manufactured date. Do they have a shelf life? If someone could let me know then I will change it to a 1 or 5 depending on the answer. I have not used them yet, do not know if I can trust them to be accurate. They are definitely inexpensive enough and a bargain if that date means nothing.

Simple strip PH testing strips
I use these for quick PH check ups, using my more elaborate PH meter is a bit of a ordeal compared to the paper strip method for quick checks on my hydroponic tanks. I use the meter when setting up the tanks for accurate PH measurements but requires 15 minutes to prep the meter, of the paper strips show my PH is way off I will then break out the meter. Found these strips to be accurate when compared to my meter readings. Good value based on the amount of strips received in the package.
