Another thing that occurs to me is that even though you can’t get the warranty for Widex from BuyHear.com, they still do offer you the 60-day money back guarantee. So at least you can still try it out with BuyHear so you’ll at least know if you really want to buy it or not without having the do the trialing locally then decide you don’t like it enough. Then all that traveling is wasted.
I know it’s not fair to do this to BuyHear (use them for trialing the Widex then not do business with them). But you can take this approach: try out the Widex Beyond with BuyHear first, return before the 60 days is up, then try out the Oticon OPN next with BuyHear. If you like the OPN better than the Beyond, BuyHear earns your business. If you like the Beyond better than the OPN, then return the OPN to BuyHear and buy the Widex locally. At least this time you already know for sure you want the Widex before you have to make your 150 miles trip to a local place.
Yes, it’s still not fair if BuyHear gets dumped in the end if you go with the Widex, but at least they have a real good shot of earning business with you on the OPN. They may be willing to bet that you may like the OPN better.
Have you asked BuyHear directly if they’ll honor the Widex warranty on their own? After all, they’re advertising 3 year warranty for Widex on their website, buying through THEM. So tell them that you saw a sticky here that says otherwise, and see what they say? If they say they’re right and the sticky is wrong, then ask them to put in writing that they can process the Widex warranty claim for you themselves, or else they will provide their own warranty for you.
