4) The coffee and espresso are great. I've learned to make a latte just like Starbuck's and I haven't been back since. Some people complain that the frother doesn't work well, but here's the trick: first, you should use non-fat or low-fat milk. For some reason, lower fat milk froths better every time; second, be sure to clean the frothing nozzle after each use. Kind of a no-brainer, I know. Third, there are two settings on the frother, and you can change the setting by sliding the sleeve on the frothing tip up or down. Experiment with this and you will get the perfect froth, really.
The IPBAS system is a special 2 step pre infusion cycle that conditions and also moistens the ground coffee to get the best flavor extraction with excellent crema topping. Thanks to the great functionality of the F50, you can brew from 1 to 16 oz cups of coffee in 5 different strength settings. It can also grind from five to max sixteen g of coffee, ranging in strength from extra mild to extra strong.
3) This machine is crazy smart. It knows exactly when to clean itself, or tells you when to start the cleaning cycle. To clean it, all you do is insert a tablet in the coffee powder drawer and it does its thing. It knows when it needs water, when the filter needs to be changed, etc. In fact, since we have a water filter built into our refrigerator, we just use that filtered water in the coffee machine and therefore we don't need to use the expensive water filters. Bottom line, if you just pay attention and clean the machine on a regular basis when it tells you to, this is a no-brainer machine.
