Renee Castillo, Senior editor
I'm the senior editor here, which mostly means I'm the one who says no. No to a fridge that made a list only because it's on sale this week. No to a freezer claim the manual quietly ties to a mild ambient temperature. No to a ranking nobody has opened since the prices moved.
Most days I have three things open side by side: the spec sheet, the owner's manual and the buyer reviews. When a listing says 45 quarts, I go looking for the interior dimensions, because the compressor step can take a real bite out of the floor and decide whether a two-liter bottle stands up. When owners keep describing the same thing (a lid seal that gives up, a display that reads warmer than their own thermometer, a fan that gets loud at night), I write it down and it ends up in the ranking notes.
I write the guides on choosing a fridge, compressor versus thermoelectric, capacity and dual zones, and I edit most of the others.
None of us has these fridges riding in the back of a truck for this site, and I'd rather say so than dress it up. We read, we compare, and we keep the lists current.
Areas of expertise
- Compressor vs. thermoelectric cooling
- Sizing: quarts, liters and usable space
- Single and dual-zone layouts
- Keeping the rankings current
How I work
- I start from the manual and the spec sheet, not the listing title. If a claim isn't in either, it stays out of the ranking.
- I read the one- and two-star reviews first, then the good ones, and look for the problems that keep coming back.
- Interior dimensions beat quart numbers. I check both before calling a fridge big enough for anything.
- When a price moves or a model disappears, the ranking gets checked again before the next update.
