I am very pleased with the Bosch induction hob I installed a few years ago. I like the way that it does not radiate heat and turns itself off when you remove a pan. My only complaint is that it did not come with a timer built in, so that I could set it to run at full power for 5 min and then at a reduced level for the next 15 min.
The one we have has 17 power levels. 1, 1.5, 2, 2.5, 3 ...... 9 Two of the 'rings' also have a boost setting.
