testmagazine.de has tested the HEYNER® Espresso GO for everyday suitability and achieved a good result.
"The compact device is a fully-fledged espresso machine in mobile take-away and mini format. An aromatic espresso is made from capsule coffee at up to 16 bar pressure. As a result, we can even attest a crema. But the taste also impresses us with a good one and a full-bodied espresso note."
"Our test subjects, including a barista, were surprised by the quality of the espresso that was delivered. The machine has no direct competitors." (source: www.testmagazine.de/heyer-espresso-go-im-alltagstest/)
