BEST SERVICE EVER!
I have bought several pairs of glasses from Firmoo and I have always been happy with both products and service. However, the last pair I bought featured their "XTRACTIVE" lens which cost quite a bit more and I wasn't happy with the result. As advertised, it does go dark, more or less immediately, as soon as you go outside, but it takes a long time to revert back to clear. I wrote a letter stating my disappointment and in reply, they requested a short video showing the darkened glasses, which I duly submitted. Thereafter, without any further ado, they offered me a voucher to the value of twice what I had paid for the glasses or a full refund. Not needing any more glasses at present, I opted for the refund which I received via my Paypal account within a few hours. Apart from immediately offering a full refund without any further hassle, I was very impressed with the way in which the whole matter was handled, right from the beginning to the end. I can thoroughly recommend Firmoo, both for their products and their service.
