Design & Build Quality
The CM1620 features a stainless steel body that feels sturdy on the counter without being overly heavy. Its compact footprint fits well in most home kitchens, though the grinder housing adds a few inches of depth. The control panel uses simple buttons and a dial for grind size, giving it a clean, modern look that blends with stainless appliances. Durability seems good after several weeks of testing, with no flex in the portafilter or tank lid. The drip tray is removable and fits nicely under cabinets, though the water tank sits at the back and requires reaching over the machine. Overall, build quality supports everyday use without feeling cheap or fragile in daily operation.
Espresso Brewing Performance
Extraction from the CM1620 produces reliable 25-30 second shots with good pressure consistency thanks to the 15-bar pump. Crema forms nicely on medium roasts, appearing thick and reddish-brown when the grind is dialed correctly. Flavor comes through clearly with bright acidity on lighter beans and balanced chocolate notes on darker ones. The built-in burr grinder offers 12 settings, allowing fine adjustments for different beans, though it takes a few pulls to find the sweet spot. Temperature stability holds well across back-to-back shots, avoiding the sour or bitter swings common in lower-end machines. Real-world testing showed repeatable results once the workflow became familiar.
Milk Frothing Performance
The steam wand on the CM1620 produces dry, velvety microfoam suitable for lattes and cappuccinos after a short learning period. It reaches proper temperature quickly and maintains steady steam pressure without sputtering. Swirling the milk in a 12-ounce pitcher yields smooth texture that pours nicely for latte art attempts. The wand angle works well for right-handed users but may require awkward positioning for lefties. Cleaning the wand after each use prevents buildup, and the automatic purge function helps keep the line clear. Overall, milk performance supports two drinks back-to-back without long waits between steaming sessions.

how to steam milk.
Ease of Use
Controls on the CM1620 are straightforward with dedicated buttons for single and double shots plus a manual mode. The grinder adjustment dial sits on the side, making mid-session changes simple. Workflow involves grinding directly into the portafilter, tamping, and locking in place, which becomes second nature after a week. Beginners may find the initial grind calibration frustrating, but the machine includes basic instructions that speed up the process. The water tank is easy to fill, and the display shows remaining volume clearly. No advanced programming is needed, keeping the experience approachable for new users while still offering enough control for enthusiasts.
Overall, the intuitive workflow makes the CM1620 approachable for beginners while still offering enough control for experienced users.
Cleaning & Maintenance
Daily cleaning of the CM1620 involves wiping the steam wand, emptying the drip tray, and running a quick water flush. The portafilter and basket remove easily for rinsing, and the grinder chute can be brushed out weekly to prevent clogs. Descaling is prompted by the machine after roughly 200 liters and uses a standard solution through the tank. Removable parts like the water tank and drip tray are dishwasher safe on the top rack. Long-term maintenance stays manageable if users follow the included schedule, though the grinder requires occasional vacuuming of grounds residue. No special tools are needed beyond a basic cleaning brush.

Who Should Avoid This Machine?
Users seeking advanced features like precise temperature control or multiple grind profiles may prefer separate grinder and machine combinations. Heavy commercial users or those making more than six drinks consecutively might outgrow the water tank and steam power. Left-handed baristas could find the wand placement frustrating enough to consider alternative layouts. People with very limited counter space should measure carefully before purchase.
