Overview
AONBOY built this fountain around a 108oz (3.2L) stainless steel reservoir with a hemispherical shape and a water level window, so you can see when it needs a refill without lifting the lid. The multi-filter setup and silent pump are aimed at keeping water fresh and the fountain quiet during the day and overnight.
It includes a water tap feature for a steady flowing stream, which some cats prefer over a still bowl. At 0.84 kilograms (about 1.85 pounds) and roughly 9.06 by 9.06 by 4.69 inches, it is sized for the larger capacity while staying manageable to move for cleaning.
Priced at $29.99, it comes with a 1 year warranty and has built up about 6,600 ratings at a 4.2 star average, with roughly 300 units bought in the past month.

Performance notes
The 3.2L stainless steel reservoir, hemispherical shape, and water level window are built for larger households that need more water on hand between refills. The multi-filter system and silent pump point to a design focused on both water freshness and quiet operation, and the water tap adds a flowing stream option.
