Mine worked once and never worked again. Continuously turns on, gets to 120 degrees and then shuts off without pulling the shot. When I requested a refund, the associate talked me into them sending a replacement instead and it was never sent. As a former barista who wanted a portable option for travel this all was very disappointing

Absolutely Love It – Coffee Anywhere, Anytime!

Color: Gray

As a true coffee lover, I’m absolutely thrilled with this portable coffee machine! It’s compact, easy to use, and makes a delicious cup every time. I can now enjoy my favorite coffee wherever I go—whether I’m traveling, at work, or just relaxing outdoors. The taste is excellent, just like from a regular machine. It’s been a game changer for my daily routine. Highly recommend to any coffee enthusiast!

Don’t buy it, bad battery and doesn’t work when plugged in

Color: Gray

I wouldn’t recommend buying it mainly cause of the battery mine died in around a year of buying it sadly. And the worst part is you can use the machine while it’s plugged in or directly from wall power so now it’s just a waste or garbage that has to be tossed sadly :(

Great for camping or when Milton visits

Color: Gray

This product is ideal for trips without electricity for folks who must have that hot cup of morning brew. The first one I got was defective but Amazon quickly rectified the situation with a replacement. Thank you Amazon. Easy to use and easy to clean, and it makes a pretty decent espresso.
