No way to know without testing with the polarized glasses and a laptop.
I even brought my laptop and glasses to two other stores hoping to find one that had one side not tempered. No luck. All the 40 breeders were not tempered on the sides though.

When you say it was difficult to pass the polarize test what do you mean?

Mine had just a few light lines show through the glasses, nothing major, but enough to tell it was tempered.
The 40 breeders and even a 15 gallon I had already let the glasses completely black out when I tested them.
Anything other than complete blackness when the glasses are rotated and I would think the panel is tempered and would not risk drilling it.
My initial test was not going completely dark but no lines that I could see. Everything I saw said that it would go completely dark when doing the test.
