Meta Glasses, what do people think

Hi,
I met someone with the meta Rayband smart glasses the other day. She really likes them, she is low vision. I really want a pair of these for Christmas, but I want to know if anyone who is totally blind has them, if so, what do you all think? Are they worth it? I know envision has smart glasses, solo has glasses coming out, but they all cost more, a lot more, out of budget more... :) Are the Meta rayband glasses any good or not?
Thanks
