Point well taken, Kekani.
Curious, OP, did you buy it new in Nov from KoAloha? If so, the warranty info that nongdam copied from their website--and I recall seeing it on there, too--is telling: if anyone buys a KoAloha from them, by all means, buy a humidifier from them. Even if you have a dozen already, it's a good faith gesture, and if someone buys one, they are more likely to use it. Particularly as it is specified in the warranty (can buy it anywhere, but shows that it was purchased if get it at the time of the uke purchase). I know this sounds a tad preachy, and I don;t intend it to be. That's just a wicked sweet uke, and everyone knows solids should be humidified (unless you live in a rain forest in Costa Rica), and the warranty is very specific about that point. That said, you owned up to it, and that's more than most would do. A+ for honesty, my fellow uker. And I recognize from your original post that you, personally, are not suggesting to send it to Koaloha.
So, what Kekani said is a reasonable consideration.
When I was a dumb 18 year old (as opposed to my current dumb 48 year old self), I bought Ray Ban aviators from LL Bean. They have a return policy: any reason, any time, for any product bought new from them that fails to meet up to the standards the purchaser expected from the product,no questions asked.
Well, I sat on the sunglasses. Put them on the couch, and a few minutes later, turned right around and sat my haunches directly on them. Mangled. I returned them. I guess my expectation was that a pair of wire framed aviators ought to support over 165 lbs. unscathed. LL Bean refunded my money, no questions asked. I feel very guilty about it to this very day. I was dead wrong. I never did such a thing again. I guess this follows along with what Kekani wrote. I'm sorry I did it.
What would I do: call KoAloha, or write them a nice letter, be as honest as you have been here, and let them decide who pays for shipping one or both ways, and how much they'll charge to repair it. Then, you have no guilt, and they will make it right, and even if it costs you some coin, you can sleep at night (unlike me and the sunglasses, which obviously still bothers me for what I did). They may surprise you in what they'll do for you, Tomahawk. But, even if they pay for shipping one way (e.g back to you), that's above and beyond considering the warranty. Cheers, all.
