Okay, so I've been using these pH strips for a few weeks now and they're honestly way more versatile than I expected. The 100-count bottle is super convenient and the airtight seal keeps them fresh.

First off - the color coding system is GENIUS. The four different colored squares make readings so much easier than those confusing single-color strips I've used before. Though heads up - they do start as different colors before reacting (which confused me at first).

I've used them for: testing my aquarium water (super accurate), settling debates about sparkling water acidity (blood orange flavor = pH4 btw), and even checking my homemade kombucha. The results match up with what I'd expect every time.

The bottle's built-in color chart is clutch, though if you're colorblind it might be tricky. The strips themselves feel sturdy - not that flimsy paper nonsense that dissolves if you look at it wrong.

Only thing to note: these are general purpose pH strips (0-14 range), so if you need super precise measurements in a specific range, you might want specialty strips. But for quick, reliable pH checks? 10/10 would recommend.

Pro tip: Store them somewhere with stable temperature - I keep mine in a kitchen cabinet away from the stove and they've held up perfectly.
