I really like it.
We have it on the network in my last school and my next school.

eg.
set up a circuit with a motor, resistor and cell.  Wind it up.  The
motor goes.
bypass the resistor.  Switch on.  Motor blows up.
Why?

The motor softare seems to simulate back emf etc.

NOW - this is a SUPPLEMENT to real time work.

http://www.phys.canterbury.ac.nz/coursework/NZIP_EdCom/MiniZippyPages/MiniZippyIndex.html
gives a couple of simple worksheets which may use CC

The demo gives a good idea of things.

(Something good can come out of the UK)
