These are pretty accurate, and easy to use. These work for any uncolored liquid. They are fast since you can read them after a second of submersion. Many others take way longer to read. I highly recommend these

Great product, it works as advertised. Using it two to three times a week to measure my acidity levels. Easy to read.

Bought this because I needed to test my urine for medical reasons related to my spinal cord injury. Was very easy to use and worked as I hoped. Does the job.

Reacts quickly. They are functional .The colors sometimes is a little hard to distinguish between the phone levels.

Really happy with these. No more worrying my ph pen isn't calibrated correctly. Takes only 2 seconds to get a reading.

They were probably made to be more accurate than regular PH paper I find them harder to figure out.
