The product is awesome. I like very much the box and rotary potensiometers quality.
I use it for my electronic lessons in approaching audio devices in real lab. I'm in face of measuring the characteristics in my private lab with a ribbon mic, DDS signal generator, digital 8Gs/s oscilloscope and Spectrum Analyser (brands for anyone, to my email). Measuring software, ofcourse, but most measures will be fully analog and self-made
The only real trouble is the potensiometers arrangement that I have to be used with (that's my 3 star in handling).
For an old time electronic like me, loving analog rotary controls, this arrangement is very very strange
