Cheap crap material Cheap crap material. You can buy their glasses on shein. Don't waste your money.

Excellent customer service Excellent customer service, answered questions quickly and resolved issue I had with a scratch on the lense easily. Really happy I purchased them and have recommended them to friends. I would opt for the gamer version as they block more blue light than the other models.

Expensive price tag on cheap quality Arrively in reasonable time, but the product itself is pretty flimsy & cheaply made. Not worth the money kooper are charging.

Worst company Worst company. They took 2 months to send me the glasses, and when I called my bank to cancel the transaction which they did and when my bank contacted them they asked to me to take back the complain and they were going to refund me. It's been 3 months now and I'm still waiting for the money. I'm not the kind of person who will put a review even if I'm not satisfied with the service but honestly I never seen something like this before.

Took a while to arrive and the glasses… Took a while to arrive and the glasses were slightly scratched in the corner. Tried to contact but got no reply
