Question: How many bars of pressure??
Document: I received one as a gift and am very happy with it. If you are a connoisseur like me you may have been shopping by bars of pressure VS: price. I was caught off guard with this one as a gift and I love it. I stopped shopping - I don't care about bars - it does the job.I paid just as much for a stainless steel Italian stove top unit that delivers weaker coffee and is harder to clean.
It can not match the pressure or the amount of crema produced by a pump driven machine. BUT it can produce a decent 'steam' espresso w/ crema ready to be made to a latte/cappuccino. The problem with the reviewers is that there are so many factors involved in why are not producing crema or a good cup. It could be the bean, the grind, the tamp, perhaps it's a cold start, not enough water, or too much water, etc etc the list goes on.
We bought this for our daughter who is going off to college. We currently have one (and have had it for many years) and it works as well now as it did from the beginning.
i didnt bought it yet. question: how many volt it can use? i wondering if its going to work outside of USA
As many folks says .This coffee maker is not strong enough to make an  expresso or a real  strong  black coffee
As for the coffee it is a solid 8/10 -- I get many complements on it from guests. The only complaint I have is the steamer. It doesn't froth particularly well, but not bad either.
Very happy with product! Works great! Easy to operate! Froths milk great for Cappucino! Replaced a Krups I had for many years with the Mr. Coffee. As good as the Krups was!
This can brew a lot of espresso. However, figuring out how many shots needed X amount of coffee was tough. It took a lot of trial and error. The milk frother is a little wimpy too. All in all, I love it!
I learned about cappuccino in a coffee shop many years ago and make it at home every morning. It's fun to make, tastes delicious using real espresso coffee, and costs a fraction of what the coffee shops charge.
I have had so many types of espresso makers over 15 yrs with some of them being very expensive.This latte maker works great, simple to use, quiet, easy to clean and makes a very good cup of latte, just as good as the most expensive one I used to use.Highly recommend this product.
Answer: This is a steam machine, not a pump one. You'll get !15 bars from a pump machine but only 3-5 bars from a steam one.
