Overview
KitchenBoss built the G300S as an 1100-watt immersion circulator with an IPX7 waterproof, stainless steel body rated from 104F to 194F, centered on a brushless DC motor the brand designs specifically to run quietly.
It circulates water at a stated 16 liters per minute to keep temperature even across a full pot, and the touch screen display is reported as intuitive to program without consulting the manual. One buyer's unit stopped working entirely after about five months with no way to open the housing to inspect it.
- 1100W with brushless DC motor, 2900 rpm
- IPX7 waterproof, #304 stainless steel construction
- 104F to 194F (40C to 90C) temperature range
- Stated 16 liter per minute water flow
Who it's for
Home cooks who want precise, hands-off temperature control for meats, eggs or vegetables, and who are sensitive to appliance noise during long cooks, are the target buyer here. Not the pick for someone who wants Bluetooth or app control, since this base model relies on the on-device touch screen.
Pros and cons
- Notably quieter than some competing circulators
- Touch screen is easy to program without the manual
- IPX7 waterproof housing can be rinsed clean
- Holds set temperature steadily over long cooks
- No Bluetooth or app control on this model
- Sealed housing can't be inspected if it fails
- Included water container may ship with the wrong lid
Performance notes
The stainless steel impeller and brushless DC motor push water at a stated 16 liters per minute, meant to keep temperature consistent throughout a pot rather than just near the unit itself.
