## At a glance

- The listing describes eight-stage reverse-osmosis filtration and mineral addition.
- Five stated temperature choices range from room temperature to 203°F.
- The 185 oz tank is divided between 135 oz of tap water and 50 oz of wastewater.

## Pros

- Countertop operation avoids plumbing installation, according to the listing.

- User manual (Included)

## A good fit for

- Apartment or kitchen users seeking a countertop RO system without plumbing installation.
- Buyers who want mineral addition and hot-water temperature presets for drinks or cooking.
- Households that can accommodate the unit's listed dimensions and manage its feed-water and wastewater tanks.

## Customer feedback

Customer feedback highlights perceived quality, taste, functionality, ease of use and temperature options. Some customers also criticize the water capacity as small and report leakage. Those concerns matter for a countertop unit with a listed 135 oz feed-water tank, especially for heavier household use. The aggregate ratings are favorable overall but include a meaningful spread of lower ratings, and they do not establish why any individual customer rated it as they did.
- Positive themes: Customers report favorable impressions of quality, taste, functionality, ease of use and hot-water options.
- Negative themes: Customers criticize the water capacity, and some report leakage.
