For the price this is a great quality hob. Its thinner than others available and heats pans up very quick. I have this in my campervan and although its a very large size, its safe to use with pans and easy to control with either wattage or temperature.
I only have a 2400w inverter when this pulls up to 2800, but the higher levels modulate their power use, so 2 pans can work well together without pulling the full power, below 1000w each the hob turns on and off to maintain temperature, so it doesnt pull a constant low wattage like built in hobs.
There are built in fans with a low level of background noise, but not an issue for cooking.
Easy to clean top and overall great value for money.
