I used a single hob in my flat to do some cooking. I have tried many other hobs, which either it takes too long to get boiling or when you turn the knob to 2 or 3 it will stop boiling completely. Lloytron E831ss Hob takes only a few minutes to boil very rapidly. And when you switch to 2 or 3, it boils rather steadily as well. The only minor downside to it is it takes a few minutes to reduce the boiling when you turn the switch from 5 to 2, which i think this is normal for every hob. This is the best hob I have used, and I have tried more than 10 types of single hobs.
