Glasses do actually work, Customer service is good and you get your answer quickly, The packaging was also very good so that it does not get damaged, After a few weeks of very hard use the plastic on the right side bent a bit i sent them a message and after only a few hours they told me they were going to send a new one thats great customer service, and i feel heard recently i havent had that good of an experience. I recommend them

The glasses are great. The case is nice and durable. The glasses where rather expaneisve, but overall a great experience.

These glasses are comfortable and easy to wear, and my vision was not diluted at all by these glasses! A must have for anyone at their computers for too long. However, one must be careful how you put on or take off the glasses, as too much repeated pressure can cause the ear-pieces to snap off.

By far the best pair of glasses i’ve owned yet, reasonably priced and quick shipping, looking forward to buying another product.

Commande passée début décembre, fêtes de fin d'année oblige, un peu de retard de livraison et difficulté de joindre le SAV (encore une fois, fêtes de fin d'année oblige). Finalement, commande reçue :) Les lunettes sont légères et ont l'air de très bonne qualité. Les verres sont très légèrement teintés, on constate directement un léger réchauffement des couleurs (filtre lumière bleue). A voir avec le temps si mes yeux sont moins fatigués (plus de 10h d'écran par jour, je devrais vite constater les effets ^^). Merci GMG

Order placed nearly 2 weeks ago. No confirmation e-mail. That was the first bad sign. 10 days before Christmas should be enough lead time, right? Wrong. A week later and still no e-mail confirmation or anything, so I use PayPal to find contact info that led (at least) to a supposed confirmation of "shipping" with tracking, but the tracking is still "waiting for package to arrive at shipper" BS. In other words, it had not yet shipped. So nearly 2 weeks later I finally get "your package has shipped".. expect arrival in 8-9 Business days. Really? Nearly a month? Unacceptable in 2022-23 without some scamming, ship from effing China BS. I expect the quality will be equally suspect, hoping to be wrong on that, but the odds are very long on that based on experience so far. Opening dispute with Paypal but they side with merchants 9/10 times, as if TIMELY delivery--by which I mean less than a month!--was not a reasonable expectation for consumers Update : after being the squeaky wheel I finally got a message from their customer service who issued a refund and apologies so I will grant them that and move from 1 to 3 stars. Still frustrated at missing gift for son but I understand delays happen. On the other hand they need to admit when domestic stock is sold out or warn customers about delays at busy time of year.
