FANTAIL is rated 4.596774193548387 out of 5 by 124.
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 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 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 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 4 out of 5 by from Best Sunglasses I've ever owned The only reason I didn't give this a 5 star is because the frames have stretched. The ear pieces fit perfectly for about 6 months, then they got loose. I got to the point that I had to wear my tether all the time so they wouldn't fall to the ground when I bend over. I am sending them in to have them fixed. With that being said, I would recommend getting the glass lenses. I have been rough on these and they don't scratch easy. I had polycorbonate before these and they scratched all over.

Rated 3 out of 5 by from Undecided Bought my fantail's ($250) last year. I bought the really good ones. Nose piece has come off. I accidently chipped 1 lens. I watched the video on how to remove the lens. One lens made it, the other cracked in half. the glass cracked on top but the plastic part of lenses is still in tacked. Im still able to wear them. But I am not very happy with the money I paid for them to only last a yr
