I sent mine back, they gave me headaches, although they worked. Maybe because I have lens implants from cataract surgery. I sent them back in July 2020, and still no money. Always a busy signal, they won't answer the phone. So, they have my glasses and my money! Scammers, I guess. They got them, I had UPS track them, they received them, but will not return money, even $60, although I sent them in less than 30 days and they had a 90-day warranty. I bought them off TV, several pairs, plus sunglasses for $60.
Length of Use: Less than 3 months
Bottom Line: No, I would not recommend this to a friend
