Second one I bought for my brothers home - very durable and long lasting product. Smooth heat settings that work for years with a gentle, pleasant adjusting mechanism. Flame is very strong too - centre one in particular is superb for stir-fries or bringing things to boil/heat quickly. Prefer the glass to enamel as it's perfectly level and doesn't chip or fade.
People complain about the water marks - homestly had no issue - just use a kitchen towel or dry microfibre cloth after if it keeps happening.
