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!

A couple of months ago I ordered the GMG Optimizer. I use it alot and it really helps terelieve stress of the eyes. Sadly the glasses got damaged (And i don't know how or why). So I sent GMG an e-mail for a replacement. Although I did not had a insurance for it they sent me a new one, because the damage was not my fault. The support was nice and friendly.

Had a really great support service with them. Easy and quite quick support service. Had a problem with a broken pair of glasses and a lost "item purchased email". Ended up quite quick and now am just waiting for a new pair.

Really happy with my glasses, I received them pretty quickly, so thats a big plus, I had no problems with anything, order, payment or delivery.

Amazing amazing amazing. First of all, the glasses are super super good. I study and spend most of my time in front of the screen and since I've been using these glasses I feel much much better. I sleep better, I feel more energic and it makes me focus and concentrate better. I bought 2 glasses a few months ago. Unfortunately, the temples broke on the glasses so i reached out to the support team and they decided to send me a new pair even though i don't have lifetime guarantee. Great service! Can recommend!
