WINNER: Menu System SINA Induction Wok (Launched October 2014). The SINA induction wok from Menu System is a compact unit, yet it still packs a powerful punch. Weighing in at just 15.6kg, this effective little cooker operates from 3kW of power for total portability and works in tandem with a lightweight wok that has a capacity of six litres. The unit features an information display and an LED status indicator, while the wok shell is made from 6mm of extra strong ceramic for enhanced durability. With height adjustable feet and a 2.2 meter cable, the work is designed for plug and play operation without any loss of performance. The product has been designed to be viewed from all sides, making it the ideal piece of light equipment to be used in a front-of-house capacity, too.
