Retail Versions

I'm going to ignore the promo ads as that doesn't reflect what the actual eventual product is. There are two versions. there are various sizes pleas check with the amiigo website for details of what is available. As far as looks goes the actual hardware is identical (as seen from a tear down of version one)

Version one (in grey/slate): This is a single piece seemless design, I'm unsure why it was changed.

Version two (in white) : note the the module is removable with a replaceable band.

Early March 2015? release the hardware part now comes in black (I don't believe this is a color choice)
