it does not heat milk or food quickly definitely not for home use we bought it mainly for our holidays for use in the car I still don't have an opinion on this so I will get back to you!!

I bought it solely because it has the ability to convert into a car heater. However, it was never used like that. As a home heater, it is incredibly slow. I had another one before (from a different company) and the speed is exactly twice as fast. If you want to warm up the baby's bottle water for anti-reflux milk (which requires very high temperatures), the child will turn purple from crying. I believe it takes so long because its resistances, since it is also intended for the car, are intentionally low. I would not recommend it for exclusive home use.
