Query: Worst coffee machine we ever bought !

We bought it last night after my other machine stopped working. we tried making coffee this morning and after half hour, the coffee was warm, not hot in the carafe...we still have the box so we will go bring it back tomorrow. don't bother with this model. it's not good. we've always used DeLonghi and our other machines lasted over two years. this particular model, well, let's just say this time we didn't get a good deal...
