Summary

A 1200 W, 0.8 L Bluetooth gooseneck kettle for pour-over coffee and tea, controlled through the VeSync app with single-degree temperature settings and scheduling. Check two things before buying: 0.8 L is small for pour-over, and the kettle has no temperature readout, so the exact temperature only appears in the app.

Strengths

  • Single-degree temperature control in the app, down to about 84°F (29°C).
  • Four presets plus a customizable MyBrew, Baby Formula mode and Delay Start up to 12 hours.
  • Hold Temp keeps water warm for 30 minutes on the base or up to 60 minutes in the app.
  • 304 food-grade stainless steel across the kettle, lid and spout, with a boil-dry cutoff below ½ cup (118 ml).
  • Feature-dense for its price, with app scheduling and precise temperature that the non-smart Original lacks.
  • Beeps when the target temperature is reached, and the sound can be turned off in the app.

Weaknesses

  • The 0.8 L capacity is small for pour-over; reviewers note little water is left to preheat a mug or carafe.
  • No temperature readout on the kettle, so the exact temperature is visible only in the app.
  • The smart features need a VeSync account and a phone, and Bluetooth pairs with one phone at a time.
  • The handle is not counterbalanced like a Fellow Stagg EKG, and the spout may disappoint flow-obsessed pour-over users.
  • No independent instrumented test of the exact CS108-NK exists; the closest lab test covers the non-smart sibling and measured 13.5°F off target at the 175°F green-tea setting.
  • Fahrenheit is the only unit shown on the base, so Celsius users must convert.

App, presets and scheduling

The kettle’s draw over the cheaper non-smart Cosori Original (CO108-NK) is the VeSync app. It adds single-degree temperature control, real-time boiling progress, a customizable MyBrew preset, Baby Formula mode, Hold Temp adjustment and Delay Start up to 12 hours, plus remote monitoring from the phone. The kettle itself only carries preset buttons and Hold Temp; the exact temperature lives in the app. Pairing is Bluetooth and limited to one phone at a time, so a multi-person household shares a single connection, and the app requires creating an account.

Temperature, boil time and lab evidence

Cosori and VeSync claim a boil in about 3–5 minutes, and Coffeeness puts it under 5 minutes. No instrumented test of this exact model exists from the major outlets. The closest evidence is TechGearLab’s comparison of the non-smart Cosori gooseneck, a sibling model: it measured a 3.6-minute boil for 500 ml of 57°F water and an excellent pour stream at 11.8 in, but 13.5°F off target at the 175°F green-tea setting, the worst of the 15 kettles tested, with only preset temperatures and no custom set point. The exact CS108-NK adds app single-degree control, so whether it behaves the same at low temperatures is unmeasured.

Capacity, size and pour-over use

At 0.8 L, the kettle leaves little headroom for a full pour-over routine; reviewers say there is not much water left to preheat a mug or carafe. The gooseneck spout works but is not the most precise for people who judge a kettle by flow rate. Cosori and the manual list the kettle at 2.57 lb and 11.6 × 9 × 7.7 in, while Coffeeness publishes 3.4 lb and 12.2 × 7.8 × 9.3 in; treat the manufacturer figures as the product and the third-party ones as unconfirmed. For larger batches or an on-kettle display, look elsewhere.

Care, running costs and warranty

Wipe the kettle and base with a soft damp cloth, keep the underside electrical socket dry, never immerse either part in water, and dry all parts after every use. Cosori recommends descaling weekly for frequent users with lemon juice or distilled vinegar, and gives baking soda plus vinegar as a quick method for thin scale. The only recurring cost is electricity, and descaling supplies are minor. No user-serviceable replacement parts for the heating element, base, lid or spout were found; the manual directs owners to Customer Support rather than repairs. The CS108-NK manual states a limited one-year warranty from Arovast, extendable by one year if the kettle is registered within 14 days, while Cosori and the VeSync store advertise a two-year limited warranty.

Is it worth it?

Cosori.com and the VeSync store list it at $77.99. At that direct price the CS108-NK is a feature-dense smart gooseneck kettle: 1200 W, 0.8 L, single-degree app control, four presets, Delay Start, extended Hold Temp and Baby Formula mode. Buyers who do not want a phone or an account should compare the non-smart Cosori Original (CO108-NK), which lacks the app functions. Because no independent measured performance data exist, the decision rests on features and build rather than verified heating or temperature-hold accuracy.

Which model this is

The app-connected Smart variant is listed under ASIN B08BFS92RP. Do not confuse it with the non-smart Cosori Original Electric Gooseneck Kettle (model CO108-NK, 5 presets, no app) or the Cosori double-wall kettle; those are different models with different specifications. The manual document code CA060120CC-M1_0520CS108-NK suggests a 2020 revision.
