Haier HAHG6BR4S2X 60cm Gas Hob - Stainless SteelGas on Metal Series 2 perfectly combines design and functionality. All components of the hob are harmoniously aligned: the new Series 2 black knobs, made of two different finishing matte and shiny match with the black glass insert and black burners. The cast iron raised grids provide either a stable support to our pots or a lighter perception of the hob.
