Part 2 of Chuck's Review. "Chuck says don't Chuck these Ray-Ban Sunglasses." September 9, 2015.Often reviews of a particular product are written by consumers who may not have all the facts, or all the complete facts are unclear, or a different set of facts apply to different models of a product manufactured by a particular company, e.g., Ray-Ban. I believe one reviewer was attempting to write an honest review. However, the reviewer also stated that a particular pair of Ray-Ban Sunglasses, by an unidentified vendor, were a scam and a copy of the original Ray-Ban Sunglasses. I took the reviewer's comments seriously. I was ready to return the Ray-Ban RB3025 112/17 Blue Lens (mirror) Aviator Sunglasses to Amazon. However, I had time to find out whether specific allegations made by the reviewer were accurate or not. Or, I had time to "sift the sense from the non-sense." I provide the following comments based on spending a little more money and purchasing several Ray-Ban Sunglasses from an authorized dealer, e.g., Amazon. I provide my recommendation on purchasing your Ray-Bans. Here is what I discovered:- The Right Sunglasses side arms (that go on your ears)= all side arms I have on each pair of authentic Ray-Ban Sunglasses have a letter (A,K,L,R...) before "CE" ?= this is correct in all Ray-Ban Sunglasses I have received.- Where is the etching "RB" located on Aviators? Is the etching RB on the inside or outside of the left eyepiece (left eyepiece is defined as when the person is wearing the "shades."). Result= In 3 pairs of Ray-Ban Aviator Sunglasses I own, the etched RB, is located by the left side of the Sunglasses hinge . In the 3 pair of Ray-Ban Aviator Sunglasses, all of the etchings are located or etched on the outside of the left Sunglasses eyepiece. However, in contrast, on a different pair of Ray-Ban's I purchased last January 2015, there was a different etching result. I purchased a completely different Ran-Ban Sunglasses style. Ray Ban placed the RB etching in a different location. For example, on the non-Aviator style of Ray-Ban Sunglasses, those different style of Ray-Bans etched the correct "RB" etching on the inside of the left eyepiece lens and further down away from the left side hinge. Yet, the different style Ray-Ban Sunglasses were authentic. Based on the foregoing, I provide my opinion. Caveat: I'm not an expert. Just a regular Joe. Conclusion: whether the etching is on the inside or outside of the left Sun-glass eyepiece is probably based on the specific Ray-Ban model, the series of numbering, when the Sunglasses were manufactured by Ray-Ban, and who is on the Ray-Ban assembly line at the particular time of production. More importantly is how the RB etching appears and looks. That is another way to tell if the Ray-Bans are authentic. You can find out what I'm talking about by going to YouTube video reviews.The reviewer stated that on the left side Sunglasses sidearm, the inscription of "RB 3025" never should have a space gap between RB and 3025 (for example). Conclusion: this is completely untrue. For example, on two official Ray-Ban Sunglasses I purchased from an official Ray-Ban authorized dealer, there are two Ray-Ban Sunglasses that have a space between the RB and the numbers 3025. In contrast, on another pair of official Ray-Ban Sunglasses I purchased, that is a different model, a different Aviator style/series, and different size-- there is no space gap between the RB and the respective number sequence. Therefore, I believe Ray-Ban changes up the number spacing, etchings on the inside or outside of the glass lens, and other minor changes to insure that those trying to copy their official Sunglasses are thrown off by the various changes. Makes sense to me.In brief. The Ray Ban Sunglasses I have are authentic but the reviewers comments on why they may be fake Ray-Bans are incorrect.I hope this information will provide you with piece of mind. My recommendation= save up a few more Benjamin's, and buy from an official authorized dealer like Amazon.Best wishes.CW.__________________________________________________________________________________________________Contessa wrote a scathing critique of the Ray-Ban 112/17 RB3025 112/17 Gold Frame Blue (Mirror) Lens Aviator 58mm Sunglasses. I don't know what vendor she is referencing since Amazon mixes different vendors who sell the same Ray-Ban Sunglasses.I just purchased these same Ray Ban 112-17 Gold Frame Blue Lens Aviator 58mm Sunglasses from the same vendor Abrahamconley. I researched the vendor and most of the customers appear happy with their purchase.I appreciate Contessa's review, but after reading how to detect a fake vs. a real pair of Ray-Ban Sunglasses, I noticed the following other factors were missing from the referenced review.YouTube reviewers mentioned additional things to look for regarding authenticy of Ray-Ban Sunglasses:-"RB" on opposite frame that has triangle on "R" and doesn't scratch off.-Has letter (A,K,L,R...) before "CE"-Paint on inside doesn't scratch off-Case is good quality and not flimsy.-Box has square bar code-Sometime comes with product manual-Cloth and warranty are of good quality materialsOther reviewers noted differences in Fake vs. Real Ray Bans, e.g.- Nose pads must be curved and aligned to the glass frames;- RB Logo on Left eye frame (when looking at the Sunglasses while held in your hand) is bright with a small gap under the upper B or Ray Ban;- The box the Ray Ban's came in, i.e., finish, sticker, etc;- Shape of the aviator eyepiece= more elongated than round;- Printing on the temples= clear and sharp, neat, and letters are straight;-Where the etching is located by the hinge? Note: I still have to find out if the etching is inside or outside, but my Ray Bans have the right style with a triangle by the R, and by the hinge;-What the booklets look like.Summary: Based on 5 or 6 YouTube Reviews, I conclude the Ray Ban 112-17 Gold Frame Blue Mirror Lens Aviator 58 mm, sold by Abrahamconley appear authentic.Regards,CW
