I have these plates for over 2 years now and I just bought an induction plate and replace ... well "there is no photo" ... I realize I wasted time and especially with electric bills this plate Riviera. all is not right to throw let honest, even if it is slow they heat regularly and have me good simmered dishes, the worries outside consumption and heating time comes mostly from buttons placed on the sides and numbered 1 to 6 are not at all visible in short impossible to know how much is heated.
