I got the B70 November of 2010. They had to send me another because mine was shorting us on the water in cups, anyway, it is the best thing that we have bought! My hubby drinks decaf and I love leaded! This waywe both get what we want and the kinds of tea, coffee, hot chocolate choices is endless....As far as keeping it on all day, I have the timer set to come on at 7:15 AM and off at 10:15.
