I been using this over a year now.
Expectation can't be too high, this give you pretty ok shots, if you want REAL coffee shots from Vivace, you get up and go Vivace.....
I rate this 5 because its portability and durability, coffee quality not so much, at most 2.5/5.
But I am impressed nonetheless, for how convenient and portable it is.
I also own other aeropress, seriously if you care about coffee that much then go actual coffee shop.
But if you want something to go and don't really care about coffee taste, this is it.
Way better than any hotel coffee, I like this better than Nespresso machine because I got good beans.
