I have the same question. I've seen references to a 1-pack, but I can't find one for sale.

@RyanEverhart789 

I have a 2 pack 

and I to need a third

but the post by th OP leads me to believing that the v2 M9 are faulty and are not produced any more hence the no updated firmware issue

v1 gets the love but v2 nothing

as mine are out of the return window I feel I am stuck with a unsuparted produce and liable to have to dump this product and look elsewhere for a systrm

@RyanEverhart789 In Norway you can buy them as 3 pack or 1 pack. I bought the 3 pack and got M9+ V2
