给咖啡机配3个加热块会更好用么？

在拍摄评测之前有看过3900的照片，但是实物的小尺寸和细节做工还是有点出乎意料的加分儿。和之前的直白3888有点类似。3900这个小方盒子对于家庭场景来说很百搭，也不会占用过大空间。
配置上的3加热片设计，对家庭场景也十分友好，虽然是配了水箱进水方式，但还是更推荐家庭进阶使用了。

Hi, I've had this machine and it is excellent but has one big problem: it doesn't warm up the group head, so it doesn't warm up the portafilter either...

[@DoreK]

hi, can you give me some informations about this machine? does it have good working three way solenoid valve (pressure release after brewing)? did you find a bottomless portafilter? temperature is stable? thanks

[@TheMartinChnnl]

@@DoreK It is a good machine for the price. Yes it has a solenoid valve. The only problem is that it doesn't heat the portafilter so coffee won't come as hot as it could. Also for light roasts it's better a machine that warms the portafilter.

@@TheMartinChnnl Thanks. Is it easy to adjust the OPV inside this machine? In the video you can see that the water flow is definitely too low at 9 bar. I am considering buying this machine.
