I made a little video talking about how these can be helpful, and showing you how to use them. Obviously I am not the most articulate speaker, which is why I stutter a lot in the video,,, but I think I still managed to get the message across! Check it out and let me know what you think!
According to the description on Amazon, these are not only just good for testing your own pH balance. You can also use them to test your drinking water, swimming pool, hydroponics (not sure what that is), coffee, and pretty much whatever else you can think of to test. I saw a video by one lady who makes her own shampoos and lotions and stuff, and uses the strips to make sure her products are pH balanced. (In the video, I used one to test some water from my fish tank, which is also a good use for them.)
Would you ever try these? Let me know what you think!
