MGM Compro Worth it or not?

[Arct1k]

I have brand new MM's direct from Castle and they appear to arm and be fine with 4S. I've been waiting for my charger to come back from being flashed but seems fine.

Looking even better now startup is supposed to be cleaner...

For warrantee there is NO better than the MM - It is a wait and see for MMM - But by the sound of it we will all be off of CC's back for a bit with this new firmware :)
