Update: 21/11/2014
After my glasses had done good service 3 years, I have lost / forgotten. As fast spare ago should I bought for longer delivery time until no new Cobra, but a Speedo Merit Mirror. The Speedo looks quite nice, and maybe it's also a matter of personal preference, but quote at least for me, the Cobra is definitely the better glasses. The eyes Rubber is much softer at the Cobra and the Speedo has a significant increase in effect or distorted vision, whereas this is not the case with the Cobra. The anti-fog coating is not better in the Speedo and has also stopped working already for the second time. Overall, I found the Speedo so uncomfortable and disturbing that I did but then again bought the Cobra. Positives: the spectacle is now already in the assembled state. Negatives: instead of plastic bag is only (as in the Speedo) a simple cloth bag here. A little tip on Arena + Speedo: at a swimming goggles in the premium segment, I expect a vernüftiges Hard Case Case, although the glasses then may cost a few euros more.
