Gardner Pet Automatic Gravity Water Dispenser, Stainless Steel, 3.85L, Grey
A quiet, cord-free waterer with a genuinely good bowl material, so long as you accept that it doesn't filter, circulate, or forgive lazy cleaning.
Best for: One- or two-pet households that want a bigger water supply for a workday or a weekend away, and owners who prefer stainless steel over plastic bowls for hygiene.

Excellent escape-artist hardware wrapped around a subscription and a coverage question Canadian buyers have to answer before they click buy.
Best for: Owners of fence-jumpers, sighthounds and door-dashers who live in strong LTE-M coverage areas and are fine paying an annual data fee on top of the collar.
