(checked 2026-10-10)5,365 ratings (1-star 5%, 2-star 2%). Amazon titles the listing 'NKBIRD WIFI Sous Vide Cooker ISV-100W'.
An inexpensive Wi-Fi cooker with buttons that Food & Wine picks for beginners and Wirecutter rates as the quietest it tested (via the near-identical ISV-200W). It heats more slowly than pricier models, its app is less polished, and Wirecutter has privacy questions about it.
Subscription: None: the Amazon listing advertises a free app with 14 preset recipes, and onboard buttons also work
Top complaints
- Slower to heat
Food & Wine says it is less powerful and took longer to reach temperature; the near-identical ISV-200W took 18 minutes to 135°F at Wirecutter. Serious Eats found an Inkbird 1,000 W model painfully slow (model not specified).
- Wi-Fi, app and durability mixed
Amazon's review summary says some owners struggle with connectivity and find the app wonky, some report temperature gauge issues, and some say it broke after six uses.
- Bulky; app privacy questions
Wirecutter says the ISV-200W is substantially larger than the Joule Turbo and raises concerns about Inkbird's unclear privacy policy and lack of public security documentation.

Wirecutter measured the ISV-100W/200W at a mere 39 dB, the quietest in its group; Amazon owners also say it runs quietly.

What experts say
- Food & Wine: Best for beginners: easy, steady and cheap, but less powerful, slower, and limited to about 4 gallons.
- Wirecutter (NYT): The ISV-200W is its affordable app-connected alternative; the ISV-100W is nearly identical, goes to 210°F and has presets on its display.
- Serious Eats: Rejected an 'InkBird Precision Sous Vide Cooker' (1,000 W) as slow and unsteady, and the old ISV-101W is no longer available; the ISV-100W itself isn't named.
