FANTAIL is rated 4.468085106382978 out of 5 by 141.
Rated 1 out of 5 by from Please listen I have had three pairs of this style and the comolding nose part has separated all three times. Each pair has lasted less than one year before coming apart. I send them back, pay the $12 repair charge and hope for the best. I requested a different style last time, but received Fantail again. I will ask for another style again. It is ridiculous to send back a $200 pair of glasses every year. Not recommended.

Rated 3 out of 5 by from Ok I bought these shades in Feb. right before summer to be ready... Ordered online, said I would have them in 3 days, got them almost a week and a half later. I was refunded shipping but still disappointed in the wait, didn't make it in time to be a present on the big day. For almost $300 you'd expect them to be flawless, but the frames of mine don't look painted all that great. In the nose frame a piece of my plastic is splintered... Overall great durable shades, honestly haven't decided if I'll buy any other pair

Rated 5 out of 5 by from Simple and durable I bought these a couple days ago with a friend, and couldn't be happier with my purchase. I got the fintail and my friend got the aviator line. Both are extremely comfortable and look great on. I do a lot of kayaking and fishing and was looking for a pair of sunglasses with great polarized lens and and a snug fit so the glasses won't fall off on rapid river's. Cheers to a great pair of glasses!

Rated 4 out of 5 by from Product Defect w Co-Molding First, let me say i will never buy any other brand of sunglasses after having owned several pairs of Costas. They are simply the best. With that said, i write this review in the hope that CDM will take note that there is a problem with the adhesive or whatever method they use for the co-molding process. In full disclosure, i have owned these for 4 years and this is the first time that it has become separated. However, many reviews seem to indicate this is a problem. i especially concur with doctorsus review.

Rated 1 out of 5 by from Achilles Heel Let me start by saying the 580g lenses are great and the glasses are comfortable. I do have a large problem with the product though. The rubber on the glasses is the Achilles heel of the product. I sent my glasses back for repair after one year of ownership and they sent me new frames. Less than a year later my glasses are doing the same thing. I do not feel that I should have to pay them to look at my glasses and I don't feel as if i should have to pay for shipping either. These glasses are expensive. I paid up front for a good product and do not feel like I should have to pay for them yearly and be without them for a month at a time. I would greatly advise you to steer clear of these glasses.

Rated 1 out of 5 by from FIX THE PROBLEM!! I'm just curious as to how many negative reviews need to be posted about all the rubber components falling off costa sunglasses before they fix the problem. I've owned both the fantail and saltbreak frames, and the rubber fell off both within a year. I love Costa lenses, but this kind of stuff has to stop if I'm going to continue shelling out $200+ for sunglasses. This ain't going to cut it folks.

Rated 1 out of 5 by from Rubber surround delaminated again This is my 4th pair of the fantail. These are great looking glasses with excellent glass. However, I have spent $48 in repair costs and around $50 in shipping to have my glasses fixed due to the rubber gasket delaminating from the frame. They are unusable after delamination. My total cost of ownership for these frames is around $350. They aren't worth $350. I have noticed many reviews with the same feeback and yet Costa continues to ship the frames and repair the frames without offering a replacement. In practice, these should be tough, fishing-proof, outdoor friendly shades. In reality, they just aren't. Try a different our. I have many costas and they are great glasses. I expect more from this brand.
