Who's using this in public?
No idea, but it protects from scratches, like any other screen protector

I know Trezor gave away free wireless charger with Trezor Safe 7 during Black Friday, that was more useful for sure.
I got the wallet on Monday, but didn't have the time to set it up yet and move my bitcoin there. I'll probably do it over the weekend and then I'll share the impressions.
No rush.
You can write a longer review with pros and cons after you used the wallet for some time.
If I remember correctly, you can write a decent product reviews.
