First, it wasn’t packed well - no padding, just upside down and loose in the flimsy box. It’s almost impossible to clean the inside, as the lid is fastened in such a way to prevent getting a hand in, & the lid isn’t removable. It heats water well - the only thing positive I can say about it. After a few mornings of using it (less than a week), the lid got stuck & was extremely difficult to open - now I’m afraid to close it so keep the lid open at all times. Probably the worst model of water heater I’ve ever had.
