I got this to try out and give my review! I am a huge coffee lover but no one else in my family is so I just make a cup of coffee at a time! That is where the 4 in 1 comes in handy! I can just make a standard mug size or even a travel mug size, and if I had visitors or my husband decided he wanted coffee that morning I can change it and make up to 5 cups at one time! It also saves space this is not a huge coffee maker it fits right in the space I have! I love how it also comes with a permanent grounds filter which saves me money and cleanup time from using paper filters! [This review was collected as part of a promotion.]
