GPJYYDS Ph Test Strip Packs, 480 Full Range Strips 1-14 Universal Ph Test Paper Litmus Soap Making Test Strips for Water Saliva Wine Urine Soil, Ph Strips and 6 Droppers

Purchased these pH strips for my A&P students. They were easy to use and read. The pH levels were what I expected, so I would include they are a functional and accurate. I love that they come in a case for easy storage. Highly recommend.

Happy to receive this product. Keeps me aware of my own ph balance but I also use them for my soap business. Easy to use.

Not my first choice in how they work but they do work. The straps fall apart and are not user friendly like other strips ive tried, personally. (The ones for Ketones from another brand for ex are better in style and usage). They work but not what I was hoping for. I am 29 weeks pregnant and wanted to see if the fluid I was leaking was amniotic fluid or urine. It seems I need a ton of fluid for it to even register as opposed to a wipe like how others work. They came out unchanged in color and mostly dry, so I didn't think it worked until I tried it with Tums (Sodium Carbonate) in water and Malic Acid in water. Def changed colours. So I guess I shall assume I am not leaking amniotic fluid and the initial test just had a neutral or slightly acidic ph for it to stay yellow. Ok! Amniotic fluid would show up as blue apparently. So I'm happy. Just wish the straps were more fortified and well put together like other brands.

Good value, quick shipping. Easy to use and read

I thought it was going to come with a chart however it did not just so anyone else who is just starting also knows this.
