This is actually the third Bonavita 5-cup I've bought in my life, one for me and I've gifted them twice. It's a simple machine, no timers or anything, but it brews a good cup of coffee if you also pick good beans. Does not have a warming element, it's a sealed carafe. I haven't really tested how long it stays warm, I have the smaller machine because I'm just making what I want to drink right away.
I prefer the smaller pot with the cone filter so the water pours over a deeper well of coffee, if we have company I just brew two pots.
Some people dislike that the filter basket stays with the pot itself and you have to put it somewhere before you can put the lid on and pour, I have a tumbler glass beside the maker that I set it on every morning, not a deal breaker for me.
I've had mine since 2017 and it's still working fine, so good return on investment too as I know people who have bought cheaper coffee makers and have to replace them every few years.
