Apexi AFC, AFC II, SAFC, SAFC 2, AFC NEO differences

[Z2TT]

Hello.

I have been browsing the internet and have found hardly any information on the differences between these models. The stranger thing is how many different variants I come across of the original AFC, some have 1 knob, some have 4 knobs.

Here's an AFC with one knob :

Now an AFC with 4 knobs :

Anybody know the difference between all the models from first to last?
Only thing I know is that SAFC has 8 tuning points and SAFC II has 12.

Thanks.
