Great Espresso Machine for Beginners
Color: Silver
Update:
Milk teamer doesn't deliver the foam like at the first couple of days, and the espresso doesn't come with the crema any longer. Somehow the pressure goes above the espresso range, and I tried to decrease the amount of coffee, and no results. I am so disappointed.
First thing that impressed me about this little espresso machine is how easy it to use. You can make a double espresso shot in literarily 1 minute. Second thing is size, the machine is pretty compact that you can place it anywhere in the kitchen without worrying about taking too much space. Also, it heats up quick, and the options are straightforward. The water tank is just the perfect size, which is excellent for me, and I don't have to refill water constantly.
Performance-wise, it feels solid and does an excellent job making shots like what you'd expect in a cafe. The water pressure is just right, delivering this espresso shot without the extra acidity. The flowmeter regulates the water evenly which is great in making that creamy espresso. Something else to note, it's small and also quiet, which is big to me since the last one was making unnecessary noise every time I make a shot. Now, the milk frother is pretty decent, and create that foam you'd love to see in your cappuccino and latte.
Overall, this is a pretty decent choice, and feels durable.

Aesthetic Distribution Tool
This distribution tool is so aesthetically pleasing. It looks great on my tamp mat that sits out on my counter. The tool does have a more delicate feel but that was not unexpected since it is basically a bunch of grouped needles. I’ve not had any of my needles break or need replaced yet (I’ve only had my tool for about two weeks now though) but there are backup needles included with the tool so I am not worried about it!
This tool is super easy to use, you just stir it gently in your grounds to fluff them. Quality tools are going to cost a bit more so I feel like the price wasn’t unreasonable.

Hefty Feel
This is a solid feeling WDT tool. It has a good weight in the hand. While it may not have the fancy push down and auto rotating mechanism, it still functions very well. The stainless steel needles are long and can easily reach the bottom of the portafilter with a magnetic dosing funnel attached.
It's a solid WDT tool for the price. Easy to clean, easy to use, looks and feel premium.
