I genuinely don't think about the toilet anymore. Three weeks in, no ring, no smell, didn't touch a brush.

Skeptical at first — but two weeks in, the limescale ring that was there for years is gone. Just gone.

The fact that it's plant-based and septic-safe sold me. Bonus: my bathroom doesn't smell like a pool anymore.

I live in hard water country. Brushed weekly, never won. One clip in the tank — and the bowl just stays clean now.
