Refund The glasses I received, I was not satisfied with them and decided to send them back and get my money back. It turned out that I had to do it at my own expense and send them to France to their warehouse. I have been waiting for the refund for 7 days and nothing, I wrote to them twice and no one responds very bad communication.

Scam Company, do not buy Months I reaches out to GMG performance to request a replacement pair of glasses. After sending the company a couple of photos of my broken glasses, GMG performance said that I did not have a warrant with them, but if I give them a good review on trust pilot, they will send me a free pair in the mail. Now a month after my previous 5 star review for them, no glasses have been sent and customer service will not respond to emails

GMG Optimizer - A Student's Review I ordered a pair of GMG Optimizer - Mat back in November 2020 because I had headaches due to my online classes and I'm glad I did. Even if we're back in school, I still use them fairly regularly for late night study sessions and movie nights. I would appreciate if the glasses were a little larger but they still work very well and I've got compliments while wearing them.

Great Glasses, just small frames or a big head. So I’ve had my glasses for about a month and change and they’re honestly great. Got the Optimizer frames and my eyes are doing a whole lot better with blue light protection. I can sleep almost immediately after playing games now and it’s fantastic. Only reason it’s not a 5 star is because the frames are a BIT small. Can’t wear my headset for a long time because they’ll destroy my ears, but after a while I’ve adjusted. Not sure if they offered bigger frames but if it’s my fault then it’s an automatic 5 and I’m just a dumbass.

One very satisfied customer Got a pair of the gold frames. Honestly can say that it has helped me avoid several migraines, as I work almost entirely on a screen on a daily basis.
