Ordered a Tough Armor and Strong Flex last night and they just shipped today.
I have never had tempered glass on any of my phones, but I decided to give it try after reading a lot about it here and on another Note 4 forum. When I tried to order the Spigen glass though, it was unavailable so I ordered one from Bear Motion. Their Note 3 glass got good enough reviews for me to give it a shot. I just hope it doesn't mess with the fingerprint scanner.
