Overall, this is a 3 out of 5 for me—it does the job but has its quirks. A tip: make sure to calibrate it properly each time for better accuracy. I appreciate the health focus, but as a perfectionist, I wish it were more dependable. Not bad, but not amazing either. 😕
- Pros: I liked how incredibly easy it was to get readings on water health in just moments, and the way it connects to my phone makes tracking changes over time super convenient. It's so lightweight and small, perfect for tossing in my bag when I'm out and about, which fits my active lifestyle well.
- Cons: As it seemed to me, the readings weren't always consistent, and I had some trouble getting it to pair reliably with my device. It feels a bit flimsy, and I worry it might not hold up with frequent use, especially around my curious little one.
