I have been using this coffee maker for a few weeks and absolutely love it! I watched  the unpacking video which was very helpful in giving a general overview of what the various buttons do. You will have a choice of size, hot/cold and strength. The machine is fairly intuitive, but there was some confusion about the priming process.  Once you use it a few times, it all makes sense.  I used to make a pot of coffee in the morning and drink it throughout the day, but now I can have fresh coffee whenever I want it. The beans are ground fresh with each cup, but there is also an option to use it with pre-ground coffee. I love that it makes hot or cold coffee and has so many different size options, from 3 oz up to 40 oz. It does take a minute to make the coffee, but it is worth the wait.  The coffee temperature is not quite as hot as my husband prefers (very hot), but for me, it is the perfect temperature. Highly recommended!
