Cant say, they have failed to deliver and are over 3 months behind schedule. They are failing to deliver their product.
Always a new reason why they have failed to ship, and they give false promises of upcoming deliveries, only to recant it later.
I wouldn't trust them and would recommend not pledging. I regret it pledging wish I had got blue light blocking glasses from somewhere reliable.Gul Rasool has never used this product.
