You can easily mix hard ingredients one after the other with the Tefal Quickchef+ HB6728, thanks to the strong 1000W power. This way, you can make the tastiest smoothies with ice and fruit. With the convenient dial, you can choose from 20 speed settings and a turbo mode. This lets you adjust the speed precisely to the preparation. Use the low setting for mixing liquids and the high setting for hard ingredients. The immersion blender also has a silent mode. With this setting, you mix with less noise.
