they work great  and are inexpensive
the ph strips ( paper) when wet show a good color match to the provided index card with ph levels on it

These work great for sending small packages and are very inexpensive. I was very pleased with the quality, strength of the poly used (they're thick enough to not rip easily) and they close easily. Great price for a great product.

strips do not indicate properly at what the PH is at. Testing with both liquid and also Ph electro tester. Not accurate

They hold paper quite well. Also the easy insert system works surprisingly well!

For exact Ph Measurements these cannot be beat. It is very easy to tell Ph down to at least an exact whole number which most Ph papers can keep you guessing on. If you really need to know Ph 3 from Ph 2 these are your best bet and lowest priced I've found.

I like these but they're a little hard to read for a couple minutes. You test it against 4 spots instead of one or two so its more accurate and its better than the ones I had before that were just paper. These have a plastic strip with 4 paper spots that will change color. I use them to test my body's pH with urine. They come with a lot! So don't expect to run out anytime soon.

My wife uses these to test the PH levels in her Vitamin C serums and seems to be pretty happy with them. These were the most cost effective strips we could find for the quantity. She tests her serum daily before using it so we needed a lot of strips.

Keep this clean after testing the PH and you will be happy with it. For the price why even complain? It works. Just don't keep the PH'ed water your testing on the meter and put it away, clean it with cleaner or diluted water.

Works great, never a problem. Thanks

Work great an SO much more inexpensive than the Miele brand ones.

They work as advertised even though they are cheap.  I believe they are a good value for the money.  I just wish the stylus tip was slightly smaller (more narrow) to be able to get into spaces between letters within words.

I used these strips to test the ph balance of my hair products.  So far the strips have not let me down and my hair condition has improved.  With these strips, I know how much to water to add to vinegar and how much cirtic acid to add to my shampoos.  My hair has been doing well since I purchased these strips.  The range from 0 to 14 also helps by offering a longer range.

In addition, the company was prompt in making sure I receive my product in no time.

The strips worked well.  The product could be improved if the acidic value was printed on each strip or a chart with the color and the ph value shown

I'm plenty familiar with litmus paper, but sometimes that just doesn't cut it. I've never used a pH strip with 4 squares for a single pH reading (I've used the multi-square ones to test pH, nitrite, nitrate, etc. for my fish tank), so this was new to me. That said, this was very easy to use. I tested these out on a new vitamin C serum I purchased, and it worked perfectly. These are great to have around the house to test drinking water, fish tanks, soil, and anything else where pH is important.

These are the best Human salvia/urine pH Test Strips that I have been able to find at a great price.  I like that I can buy them on Amazon.com for the lowest price anywhere, plus I get a bonus of free shipping.

Any pH testing strip is designed to be used for a specific purpose by individuals who have enough knowledge to know how and why they are using it.  These particular pH test strips are designed to be used by humans who are striving to improve their overall health by frequently monitoring the alkaline/acid level of their saliva and urine as part of medical direction that is typically given by a Health Care Provider.

In order to raise the alkaline level for better health, lifestyle changes such as diet and exercise must be addressed.  All of the foods and other substances, that we all put into our bodies, have drastic affects (either good or bad) on our pH levels, and on our overall health.  There are items like Alkaline Food Charts and natural supplements that can be helpful, and such items can be found on Amazon,com and at other locations on the Internet.

This is the first time we have used this strips. We were hesitant at first, but are extremely pleased at how well they work. I would definitely purchase these again.

This is an inexpensive pH probe from Oakton. I purchased it for a new Acorn 5 that I purchased recently as it didn't come with one.  The probe works as expected.  It comes with instructions and is easy to install on the meter.

Even though they aren't super high-quality, they didn't break and all of them work perfectly. I bought them to give as gifts to my laboratory co-workers (and phlebotomist especially) during Medical Laboratory Professionals Week.  Everyone wanted one.  I see still see people using them in the lab and lab week was in April.  Great pens and inexpensive for the novelty and quality.
