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

Very good product I highly recommend I… Very good product I highly recommend I no longer have a single problem thank you GMC performance

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.

GMG Optimizer - Mat I purchased of pair of the GMG Optimizer - Mats to wear while working from home towards the end of 2020. I had noticed myself starting to get minor headaches from staring at my screens all day and saw an ad for a discount on these glasses from a YouTuber around the same time. I decided to take a chance on them and I am happy I did. I was able to work long hours (CPA at big accounting firm) and no longer experienced headaches from my screens. Same goes for gaming. Often, after clocking out, I'd immediately hop in a 1-3 hour gaming session - and the glasses performed well there as well. I definitely recommend giving these a try if you experience headaches from your screens.

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.
