(checked 2026-10-10)Small sample: 1,077 ratings (1-star 16%, 2-star 3%). The older Nano 2.0 listing (B07C7PW3PC) has about 15,000 ratings but is a different model.
A compact, accurate Anova that Serious Eats and Food & Wine pick for value. It heats more slowly than the full-size 3.0, its fixed clamp limits which pots you can use, and 19% of Amazon ratings are 1-2 stars, many citing Wi-Fi and app problems.
Subscription: Optional: Wirecutter says the Nano also needs Anova's app subscription ($2/month or $10/year) for remote control, notifications and recipes; the onboard buttons work without it
Top complaints
- Fixed clamp limits pots
Wirecutter, Serious Eats and Food & Wine all note the clamp isn't adjustable; Serious Eats found it harder to secure to a Dutch oven, and Food & Wine says wide vessels may need a lot of water.
- Wi-Fi and app problems
Amazon's review summary says many owners have trouble connecting to Wi-Fi and find the app unreliable; Wirecutter notes remote control needs a paid subscription.
- Slower to heat; quiet beeps
Its weaker element took 17 minutes to 135°F vs. 13 for the 3.0 (Wirecutter), and about 20% longer in Food & Wine's test. Serious Eats wishes its beeps were louder.
What owners love
- Holds temperature precisely
Serious Eats says it holds a bath without wavering a degree; Food & Wine measured less than one degree of variation; Wirecutter found it as accurate as the 3.0.
- Compact and light
About half a pound lighter than the 3.0 and easier to store (Wirecutter); Food & Wine quotes chef Richard Blais using it for travel.

Serious Eats says the app paired seamlessly every time; it uses the same app and recipes as the 3.0 (Wirecutter).

What experts say
- Serious Eats: Best under $100: holds temperature without wavering; fixed clamp and quiet beeps.
- Food & Wine: Best value: precise and easy to set up, but less powerful and the clamp isn't adjustable.
- Wirecutter (NYT): Alternative: as accurate as the 3.0 and a minute faster than the Monoprice, but slower than the 3.0 and needs the app subscription for remote use.
