Coffee maker works perfectly but I wish I had known that it took so long to make coffee. Maybe this is true of all the 12 volts but I was surprised when I read on the box that it could take 30 min to brew a pot. But even more surprised when it took over an hour. I wanted this to use on our boat but I guess bringing a thermos is a better option
