Butterfly is so pro it could sing in LaScala - Milan.
Positive Product Points
Ultimate industrial design - no unnecessary decoration, pure clean straight line look, polished steel/chrome finish, built quality, minimalistic simplicity of use, consistent great shots, short heat up time (for HX machine)
Negative Product Points
Nothing negative with exception for bit noisy pump action, but this should not be really of any significance. I posted it rather to give at least something negative to this otherwise positive opinion.
What a machine! Firstly I read other reviews on this site about this machine, indeed discovering it for myself from among all these Isomacs Teas, Milleniums, ECMs Giottos, Andrejas etc., and after checking other websites I could not any longer resist the beauty of these clean lines design (absolutely best looking espresso machine to me), moreover superb built quality pointed by fellow reviewers.
I do not intend to get technical, this can be found in other reviews and other Websites. This is my impression on Butterfly. To begin with this is best looking espresso machine to me, steel/chrome looks, fantastic industrial design, nothing unnecessary, everything in place, minimalistic boxy shape, simply - beauty. Removable by handy steel rail top for water filling with cups in place, which do not have to be removed. Only neccesary regulators, standard for HX and full professional E-61 group. Drip tray very big, easy to remove. And you can choose color and finish of side/back panels, available in black mat (very interesting look), grey etc. or all polished stainless steel or even gold and you can change it everytime you want. Who else can offer that?
Operations. Easiest as it could be - it works for me on timer. No need for extra moves like pulling steam, or water, checking boiler water levels like many other machines require to do. The only thing you check is water level in water reservoir every second day and even this is secured by automatic switch off. My Butterfly switches on via timer and after 15-17 minutes you can shoot (short time as for HX E-61). But this is really not important as it works for me on timer so it is ready whenever I want it to be. After easy adjustment of presurestat to 1,1-1,2 bar it takes only about 100ml of water to be flushed before shot when the machine stays on for hours. My wife can now enjoy shooting espresso for herself, easy. Quality of shots - unbeliveable, thick crema espresso like honey after short adjusting grind ( Isomac Machinino) and tamping. And consistency - shot after shot deep red brown thick espresso, using always 100% Arabicas. And this natural sweetness of shots so creamy like never before. Technically thanks to David Schomer articles. Moreover steaming milk every morning for first capuccino ( always capucciono first in the morning than espresso - matter of escalating taste intensivity) is like never before - consistent glassy looking (after hand swirl) microfoam, again David Schomer lessons.
Butterfly wins with Andreja and Tea (I have tried this one), because it has all the features they have, but it is more design oriented as other two are to flashy, to much decorated. Butterfly is military tank quality machine, definitely no extra manouvers machine, easy to use, no hidden hand triks to control it, just lock and pull situation. Everything on demand like HX - power, steam, water and this gigantic chrome E-61 group up in polished steel front. Gorgeous.
My buying experience was absolutely all by accident. After finding via Web - LaScala service/rep in Warsaw/Poland I found Butterfly on their website picture, picked up a phone, it was the only one they had, so I talked them into selling it to me after year of using it in house by them. So next week it became mine for great price of $600 for practically new machine right after breaking period.
