So my wonderful, and very expensive water filter died on me during my last camping trip. An internal component snapped - something I couldn't replace or repair.
I walked into a MEC store, explained the situation, showed them the damage. The response was an immediate 'yep, we'll warranty that'. They didn't have a replacement in store so they gave me a gift card for the full amount and got me on the phone with MEC's online ordering center to have a new one shipped to me. I was in the store on Saturday, and the replacement arrived at my office today. I bought the filter almost 3 years ago.
I don't imagine MEC's warranty is news to anyone on this forum, but what would have been a super-expensive bit of equipment failure was instead a reminder that the cheapest source for a product isn't always the smartest one.
