Really amazing coffee machine! Fantastic design and easy operation. There are just a 2 buttons for filter and pour over style coffee brewing. Mainly made of glass and aluminium-just a couple plastic parts in total. Brewing process is very simple-just fill up with water and pour some coffee and you're ready to go! Based on my non-professional tests, the taste is great as it should be and the temperature is also great. It makes 1litre coffee from a cold start in about 7-8 minutes which is fine i guess. Firstly it boils the water till optimal temperature and only then a valve opens and water starts to flow over the coffee. After brewing is done the machine beeps 3 times which lets you know that everything is done and you can enjoy your perfect coffee cup! For this machine i use 1x4 size very popular coffee paper filters which are widely available and not really expensive. Overall im really happy with this machine! Respect to Delonghi!
