VA panels aren't great (they're fine, just not great). 350 nits also isn't great. Most people are probably looking for more. It's also pretty overpriced, but I guess that's the price of privacy?
Yours is the first comment in the hundred I've read that links a concrete product. I can't vouch for it, but kudos to you.
