## Customer feedback

Customer feedback reports effective filtration, pleasant-tasting water and an attractive appearance. Experiences are mixed on reliability, size, refill time and value, with some reporting that the unit stops working, finding it small or slow, or considering it expensive. For buyers weighing this against the listed 5-liter capacity and countertop design, the reports suggest that fit and pace may depend on expectations, while reliability remains a concern in the feedback. Ratings skew positive overall but include a notable one-star share, so they do not establish consistent performance for every buyer.

- Negative themes: Some customer feedback reports leakage.
- Mixed feedback: Feedback is mixed on reliability, including reports that the filter works well and reports that it stops working.
