You google for "plastic taste Petra" or the like, can be found though many postings, calling to, it goes in this thread but it is always a question that someone has just changed from another company for plastic taste to Petra and is now totally happy.
I have therefore decided to use this Petra machines and regret not (have the engine now 6 months).
She looks totally pretty, easy to clean and foams also soy milk or rice milk frothy easily!
And most of all I am pleased with hot frothed soy milk and cocoa in the evening, which is made in 2 minutes, and the oven can remain cold :-)
All nozzle components for the milk froth can be quickly removed and so very easy to clean.
I would recommend this machine to anyone immediately.
