Thanks again, GMG! My glasses had broken recently, and I saw they had a lifetime guarantee. Turns out you had to purchase it, which I had not. Despite this, they made an exception and sent another pair! I'm very pleased how accommodating GMG is!

I want to thank GMG for coming through and providing excellent customer service. I had an issue with my pair of Optimizers where the lenses seemed to be a little cracked. One day I was taking them off, and they totally just snapped. I emailed customer service and they are sending me a new pair. I am giving them 5 stars because they are totally coming through and warranting their product. THANKS!

I purchased the GMG Optimizer - FG1019-Mat glasses and used them while working from home. The glasses have been comfortable to wear. I'm not sure if they actually help or if its a placebo but it makes me feel better at least. The glasses broke on the frame after a couple of months. I reached out to GMG Performance via e-mail. They responded quickly and were very friendly. They offered to replace my glasses and I just received the replacement today relatively quickly. Very positive experience.

Very very nice in allowing me to get a repaired price out of kindness.

Great glasses and great customer service.

Amazing customer service and really quick to reply! Amazing quality on the glasses aswell, will definetly recommend to friends and family. :)

I lost my pair on a airplane and after talking with them the gave me a discount on the pair I have now they made sure I was a happy camper and they did great people to deal with

Had the GMG Optimizer glasses for 5 months now , absolute MUST for people working in front of a screen for long hours. After repeated use one of the arms broke off unfortunately but the customer support was of huge help <3. In summary : amazing !!!
