Casabrews Espresso Machine

This Casabrews espresso machine comes with a portafilter and filter basket. It has a stainless steel finish and a built-in pressure gauge. The unit is approximately 30 cm by 15 cm by 30 cm (11.8" by 5.9" by 11.8"). Note:milk frother works but leaks a little bit water . I just don’t know how to use it . 🙈
