Reliable coffee machines are ones that hold up and perform well for a decent period of time. Surprisingly, lower-end inexpensive coffee makers tend to rate higher for reliability than pricier ones: most of the top rated products in this category cost under $100.
Still, many luxury brands receive great scores for this factor, including BUNN and Zojirushi. Among the low-cost manufacturers, Proctor Silex is one of the users' favorites.
Users report that programmable coffee makers tend to be significantly less reliable than programmable ones. In addition, smaller models with lower capacities (4 and 5-cup models in particular) reportedly hold up better through the years. You might be happy to hear that the top-ranked models here are also highly rated for their quiet operation, which is ideal for early risers.
