Hi,

In the UK there is no mention of a specific time in reguards to warranties, it just says "a reasonable time for the product" and is capped at 6 years. So you can ignore the 1 year warranty, it's just a red herring!

As for the product being imported, in this case it is not important, as in the UK the contract is between you can the vendor (ie Amazon or Mann etc...) so if it bought from a UK vendor is would be down to them to argue with Rio not you.

On the other hand if you imported it yourself they you would have to do the dealing with Rio in the US, and if Rio UK decided to honour it here then great but they are under no obligation to do so.

I got all this info from my local Trading Standards Office before I bought my Karma

Cheers

Cris.
