Pros

Stainless steel construction is a practical alternative for buyers who prefer a metal fountain to plastic models.
The 2.6-litre capacity and visible water-level window make routine water checks easier.
The package list specifies six filters and three sponges, giving buyers replacement filtration pieces to start with.

Cons

Corded power means the fountain needs to be positioned near a suitable power connection.
Customer feedback includes reports of units stopping after a few weeks, so reliability may be a concern for buyers prioritising long service life.
