I've needed to test the other side of their "Fast Delivery. No Worries Returns" mantra lately, with a cheap reel bought a few months ago that has a basket case anti-reverse and needs to go back. It has been relegated to catching livebait but I did have to use it to catch a kingi (which was a neat challenge with no anti-reverse).
Today is the 10th day since requesting a return authorisation via their website. The second day since direct messaging them on Facebook to ask what's up and being told they'd get back to me.
It's a crazy time of year so I wasn't expecting the same superb speed as when ordering, but it is nonetheless informative seeing how the service side of the equation plays out. Especially in light of Marine Deals clearly provisioning the manpower to keep taking and filling orders over the same period.
Perhaps we should run a comp with a prize. I'll give my favourite Kingi-slayer Shimano Eclipse rod to the first person who guesses correctly how long it will take for the "No Worries Returns" to be resolved. Today is the 10th day, so if you are listing a guess, it better be 10 or more

I'll kick this off with my guess: 15 days.
The winning guesser gets this rod, sans reel.
