I was going to order the Torras over the UltraGlass due to the 1 year warranty that you mentioned on their product description, but was bummed that it wouldn't arrive until 3 days from now.The packaging and glass appear to be identical, but the only difference on the Amazon listing is Torras offers a year warranty on their product but UltraGlass doesn't mention any coverage.
After looking deeper, I found a Q&A/Review section of the UltraGlass where a customer recorded a video of the warranty QR code that comes inside the packaging of the UltraGlass, saying that they found out that as long as you scan the QR code to register your UltraGlass screen protector online, there is a lifetime warranty.
I just ordered the UltraGlass instead, and it arrives tomorrow!
