I purchased from SmartBuyGlasses based on the reviews I read online. Big, big mistake! This company has got to be the most unprofessional online merchant since the World Wide Web began around 1991. They offer a 100 day guarantee/return policy. I chose to exercise this option after receiving some eyewear from them that was simply not Tom Ford quality. Absolutely counterfeit! That was not my main concern. My focus after receiving this pair of imitation Tom Ford's was to just get my $300.00 back into my account. They will ignore your e-mail, hoping you just give up and keep your eyewear. I sent one e-mail in which I totally implored them to not ignore this e-mail, I literally begged them, how pathetic is that. Finally, I must have punched through to a sympathetic employee at SmartBuyGlasses. I was actually provided with some assistance and a return form. I was so happy just to have made a little progress. I'll cut to the chase. If you opt for an exchange or refund, this is the process. Be prepared to send over a dozen e-mails. Expect to get a different representative, when they do finally respond that needs to hear your reason for the return all over again. You will questioned, almost interrogated as to your reason for the return. Whatever you do, do not state that you believe they're imitations! You will need to provide digital pics. Once you finally get the green light for the return process to begin, expect even longer delays. There was virtually no communication as to the whereabouts of my return once I mailed them out. You just have to sit, cross your fingers and wait. A worthy mention here, I had to pay for shipping! After an excruciating return process I finally received reimbursement. But wait, it gets better! I sent $307 to SmartBuyGlasses initially. My monetary reimbursement was in the amout of $262. After all this, I was shortchanged! Plus I paid for shipping. Their favorable online reviews are most definitely phony, not a doubt in my mind. This is the eyeglass company from hell, worst online vendor I have ever encountered and I have been online shopping for decades. Okay, I have vented, waited a long time to find the time to type this. I do feel a little better. I'm about $50 lighter and without new eyewear but lesson learned. Don't do business outside of the USA. SmartBuyGlasses is a Hong Kong based company.
