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.

Trash scam company After they got my money they went completely silent don't bother about my order anymore, it has been a week now and they even didn't ship it yet and no track number! this is ridiculous, don't buy from them! Upd: They are completely ignoring me now, no information about my order no tracking number provide. Trash company, don't want to refund me

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.

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

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.
