Experience with Madell CA4810A Transistor Curve Tracer

My preferred seller of semiconductors honored me to ask my opinion about this curve tracer...

Madell CA4810A Transistor Curve Tracer

Madell Technology Corporation

I personally use the curve tracer from locky_z, so the honor is much too big, but why not help a distributor not to sell fakes.......:D

thanks for any information....:)
