Just got back from speaking with the NOLAN rep about my helmets visor, basically the helmet visor has become very badly scratched between the anti fog mechanism and the external visor. (the inner anti fog visor has been rubbing the external visor causing scratches between the visor and the fog layer) I know the helmet is getting old (4 years) and expect wear and tear, however, this issue was directly caused by Nolan's own device/equipment and has reduced the life of the visor in general. In other words I donâ€™t expect something I bought from Nolan would reduce another part of the helmets lifespanâ€¦ these scratches where also noticeable half way though the helmets life less than a few years into it, i didn't realize there was a guarantee at that time. I bought the defective visor into the shop the rep was visiting because I found that the helmet visor had a 5 year scratch warranty (after finding some old paperwork), which now I understand after talking to the rep(which is why Iâ€™m so annoyed ), apparently doesnâ€™t cover these types of scratchesâ€¦ if it doesnâ€™t cover these types of scratches what does it cover!?!? The anti fog system was on as tightly as it could be but still allowed movement. This is a design fault. They do have a warning (in the fine print) stating â€œthe presence of dust between the visors can produce scratches on both surfacesâ€ which the rep was quick to point out... hmm thanks for the warning Nolan ill be sure to ride my bike only in dust free areas from now on! Look out scientific dustless facilities here I come! So in short Iâ€™m not happy with Nolan, one part has reduced the lifespan of the visor, new visor is 55 bux plus I want a tinted one another 55 buxâ€¦ I think ill just put the 110 dollars towards a new helmet(one that comes with a tinted visor)â€¦ and guess whatâ€¦ it wont be a Nolan one!
