I never have written a review before this but after purchasing this product from seller TheAspecs, I feel obligated to! Firstly I would like to briefly mention that the sunglasses themselves are great! I would definitely say that these Persols take the cake as my favorite out of all of my other shades, besides the look and appeal, the quality of the glasses is phenomenal, the craftsmanship is great, you can see right away that they are made to last and build from the finest materials, built strong and if treated right will last a long time, you get what you pay for and there's a reason why these are on the upscale class of sunglasses and why so many celebrities wear them, their luxurious and will always be a classic staple item that will never go out of style! Now, for the seller that I purchased these from, TheAspecs, their customer service was outstanding and so refreshing to work with!! Michelle was so sweet and patient and was extremely helpful making sure to answer all my questions and help with any requests I had! I decided to exchange the pair for the 714's (pretty much look the same except the 714's are made to fold), Michelle was very understanding and gladly sent the 714's to me with a prepaid return label to sent back the 649's. They are a small company, it was so refreshing to deal with a mom and pops type shop who actually showed that they care about their customers and respect them and appreciate their business, I can assure you that if I had purchased these from a big brand company, I would NOT have gotten the same treatment and care! Not to mention I would have not paid as low as I did for these glasses! I paid basically half for them of what I would have spent at any retailer, and I can assure you that the product is 100% authentic! Comes with the tags, case, stickers, certificate of authenticity and all! I would purchase from them again with pleasure and would recommend anyone else to buy from them in a heartbeat!
