Nice glasses, good service after something went wrong with the transport. I would recommend it!

very good service and quick response

Great glasses and exceptional customer service to replace a broke part for free!

Great glasses and function properly. Look good and are comfortable. Customer support is amazing. The glasses did however break over time, so I recommend getting the lifetime warranty.

These glasses are fantastic! I work behind a screen then game afterwards. I was dealing with eye fatigue/dryness, headaches, and trouble sleeping. I tried a few brands of blue light blockers, and none hold up to GMG. Not only do they look stylish, but they'll help your eyes not feel terrible after extended sessions behind a screen. I definitely recommend for anyone that works at a computer or likes to game.

Paires de lunettes qui fonctionne très en travaillant avec un ordinateur, fatigue visuel inexistant. Elle sont de plus confortable, et ils proposent différentes formes de lunettes pour satisfaire tout le monde.

My glasses broke after a few months of using them during my workdays. GMG agreed to replace them with no hassle and I couldn't be more impressed. The glasses fit my face great (and I have a big ol' face) and do what they're intended to do perfectly. Great buy and would recommend. Shout out to solid, responsive customer support staff!

The glasses are great and allow me to sit before a screen for longer than I normally would. It helps a lot against bright lights that come through. GMG also has a great customer support and when I encountered a problem they were quick to fix it. Thank you so much for a great product!
