I’ve read many of the reviews here and I can relate to some of the issues. Technically this coffee maker is fine if you stick to rigid guidelines. 1st, don’t use paper filters. Use the gold mesh variety. 2nd, keep those cones very clean. Have 2 and rotate by washing in dishwasher - hold it to the light and if you can’t see clearly through it the coffee won’t pass fast enough and it WILL CLOG. 3rd and MOST important, use ONLY a maximum of 6 LEVEL scoops (with provided scoop) otherwise you will have grinds overflow and it will appear to “leak”. If you follow these directions your coffee maker makes a  delicious cup of joe. However! If you like HOT coffee 190-200F buy another brand. This maker brews at around 180ish and holds at about 165 for a couple hours - which sounds hot but trust me and test for yourself, it’s NOT hot enough.
