I waited to write this review... and after using the Carafe for a month... I LOVE it! Compact, fits under my cupboards & the water tastes great! I did purchase the alkaline mineral boost filter. I'm saving a LOT of money, no longer purchasing bottled Spring Water! My upper cabinets do not allow for the sliding tray :( But, I placed one of my 100% cotton reusable paper towels under the carafe and it slides in/out from the back of the counter just fine! :) Another tip for you... is to check out the cool Mason Jar handle & pour lids! I keep 1 or 2 quart jars of my Carafe water in them... as well as keeping the Carafe full. That way I have plenty of water for my 6-cup coffee maker, etc... The last note I have is in regards to the "speed" of the reverse osmosis process. Seriously, it only takes about 10 minutes. Super fast!!!... and quiet! Have a great day! Renee
