I recently received delivery on an upgrade for a GO2A SE. What I notice is that the case does not indicate in any way that it is the SE version like the one that I had sent in for the upgrade. The description on the receipt states "LH Labs GO2A Signature Upgrade". But, the only marking on the case is "GO2A". There is no 'SE' designation on the case. Any way to tell the difference between the two?
