Reviewers mostly praise the PETLIBRO Dockstream 2 Smart Fountain for its pumpless design and app-based hydration tracking that logs each pet's water intake. Owners love the 3-liter capacity and four-layer filtration, which provide fresh, clean water even when away, and the cordless version runs about 30 days per charge for placement anywhere. Some users note the design changes feel incremental and the app adds complexity, but overall it's a fuss-free upgrade for concerned pet parents.
