Love MarsQuest!
I have several pairs of MarsQuest glasses and I love all of them! Their metal frames are especially lightweight and comfortable to wear.
On my last order I guess a pair I ordered was out of stock so they refunded my money for that pair the next day, but no communication about why. So it wasn't until I received the package that I realized what must have happened. Seemed like poor communication, but it would NOT stop me from ordering more sunglasses from them!
