Must have for coffee drinkers will love
The coffee drinkers wet dream. This works so well and it one of the best additions to our house. The ease of use and the way it works make my husband and son just love their coffee. I don't drink coffee but I know this machine is too notch as they swear by this. Quality as well as workmanship are bar none.

Solid, but not without fault.
Got it on sale for 90$ and honestly it’s been pretty solid. After making espresso, the grounds are always left watery, but that’s just a design fault in trying to achieve more pressure. The coffee is pretty consistent and solid, a pretty good value for what it is.
My main issue is that it leaks water now randomly after about a year of use, which ultimately warped the coffee station it sat on. I know some bigger brands that begin leaking after time as well. So for under 100$, I got what I paid for. this saw some heavy use and got the job done. Probably wouldn’t buy again though.

Worth a lot more than I paid!
I waited a year before making this review. I could not be more impressed with how well this machine has been performing, regardless of its low price. I have been making two or three americacano's a day for a year. Every cup is just like the last. It takes about 90 seconds to have a hot eight ounce americacano! The only time it leaks is if I grind the beans too fine. Once I dial in my grinder, Im set until I switch to different bean. I feel like I have already got my moneys worth. If it died tomorrow, I would order another one.

The coffee is very tasty
This 20-bar espresso machine is compact, stylish, and very easy to use. It makes great-tasting coffee with a nice crema, and the steam wand works perfectly for cappuccinos and lattes. The water tank is spacious and convenient, and the display showing brew time and water temperature gives it a modern touch. Perfect for enjoying great coffee at home without taking up much space… I’m in love with my coffee maker 😍

Wonderful so far! UPDATED REVIEW: little over a month later...
Reducing to 1* due to machine being defective. No longer exerting enough pressure for good shots and the portafilter has started leaking. I've done all troubleshooting and steps that should be taken for these issues to no success. Machine is basically a hot water machine now.
4.5*
The warmer on top could certainly be better but other than that I haven't had any issues. Seems to be as advertised. It's definitely quieter than my nespresso machine and makes a better shot for sure. Getting the grind and tamping right takes a bit of trial and error if you're new to making espresso but once you get that down, this machine will do what you need. The Americano option is also a little wonky imo but I haven't messed with it very much. I just run my shots and use the hot water function when I make an americano 🤷🏻♀️ as long as it lasts it seems like it's gonna be a great purchase 😌
