“He is a very kind person, but his teaching is hard to follow. He teaches from slides and sometimes explains circuits verbally, saying "it's done like this, like this," so we often don't understand what's happening.

He has deep knowledge of analog and digital electronics, both in theory and in practical work, and his theoretical understanding is at an expert level.”
