works perfectly! extremely clean inside. it's commercial and really well built. would last years. heats up much faster than 12v versions. it could be used in a home office / camper / man cave environment or anywhere really. easy cups of coffee or tea. simply plug it into a normal socket from an inverter or portable power station and it'll efficiently heat up water. it also can auto heat the water if it drops in temperature so you can always have hot water ready. have a look at the photos, any questions please ask thanks
