As someone who runs a small cafe, I was skeptical about these test strips at first. But after using them daily for a month, I'm genuinely impressed!

The Good: The 1-second dip time is legit - no waiting around like with other brands. The color chart is super clear, and I love that the entire strip reacts (you can easily cut them in half for double the tests). They matched perfectly with our Steramine tablet solutions.

Real-World Use: Every morning during prep, we test our sanitizer buckets. Seeing that instant 200ppm confirmation gives me peace of mind before health inspections. Pro tip: Keep the vial in your apron pocket - it's become my most used tool!

Watch Out For: Like one reviewer mentioned, there's no way to 100% verify accuracy (but ours consistently matched our dilution calculations). Also - CRUCIAL NOTE - these won't work for chlorine/bleach solutions.

Final Verdict: At this price point ($0.10 per test if you cut strips), they're a no-brainer for food service. Way more reliable than guessing concentrations, and way cheaper than failed health inspections!
