Genial gracias

Very good product

Very nicely packaged and a good value for the money. These pH test strips cover a very broad pH range but are not well suited for precise measurements.

Ni funciona como esperaba, he visto comentarios que indican que se debe hacer price as de goteo, aún no los he robado de esa manera

I used these for a science experiment for my classroom and they worked great! They like to stick together, my students would rip off 2-3 at a time without even noticing.

Impossible to tell difference after using for either saliva or urine. The strips are dark orange. I have used for 4 days now, for both saliva and urine and I can’t see ANY difference because the strips are a dark orange color.
