Been working in coffee for several years now. It started as a hobby which means I have about 6 different ways of making coffee at home. All that to say I can find very little wrong with these machines as long as your beans are decent quality and you're grinding fresh for each pot.
Yes they rarely have any form of temp control and the hot plate leaves coffee tasting stale after a few hours of keeping it warm, but they're consistent, albeit consistently mediocre.
And they come with the added bonus of being able to schedule the brew time which can be helpful for those rushed mornings.
