KAPO K2 is a fantastic tool for people on the go. The fact it boils its own water is mind-blowing. I enjoy the taste of espresso I get out of it.
That being said, it has its shortcomings, for which I'm removing 1 star. Firstly, the provided stock basket doesn't have perfectly straight walls, they sort of cone inwards. With lower doses, my tamper gets stuck every time, and that's very annoying. Secondly, the programmable options are fantastic, but it pains me to see the unused potential of profiling your shots even more precisely, with specific steps being able to be set, more control over each variable during the extraction (I'd like to set preinfusion flow rate separately from the actual extraction) and so on.
All in all, it's a fantastic tool for what it is and what it offers. There's no debate it has earned its place on my counter, everywhere I go. I'm just looking forward to advanced water pump controls and software updates which would allow precise, real-time tweaks of the water flow and steps to be set and followed. The stock basket is alright, but it could've been a tad better.
