- Same proven dock-and-run design
- Motion sensor included
- BPA-free
Cons
- Same 30-day battery as original

- Full stainless steel — not just a tray
- 50-day battery
- Ultra-quiet ~25 dB

- Water-electricity separation design
- Motion sensor with long variable battery life
- Most researched wireless fountain
Cons
