Hey, you can visit Kenwood showroom itself. either they would replace it with a new blender and charge something or would suggest you some stores. If not Kenwood showroom you can go to some store where they sell kitchen appliances.
I have just unfortunately smashed the glass blender part of my Kenwood kitchen machine- does anyone know where I could get a replacement bit in Dubai without having to go the whole hog and buy a new mixer?
Also, how much the new jar will cost?
