I want to give a big thumbs up to Henry at Wilderness Equipment for his excellent customer service.
I have a First Arrow UL tent, which I LOVE.
I've had it for about 5 years, but due to circumstances beyond my control, I haven't used it much. After only about 25 - 30 nights' use, the main zip that closes the base of the inner failed. The zip coil somehow broke (???), and the sliders came off both ends of the double-ended zip. That left us with an unclose-able billowy inner and a gaping hole, on night 2 of a remote, exposed 8 day walk in Tassie. A clever repair by my tent-mate had us back in business, though with a little too much fabric one end, and not quite enough at the other.
When I got home, I contacted Henry, and sent a photo of the repair. After a couple of weeks when I thought he was avoiding me (he wasn't, he was out bush, and had technological hassles), I was able to speak with him. He sent a new inner to replace the damaged one, as the particular zip is complicated to replace. Express post, it arrived in NW Tasmania within 2 business days.
I know the tent is pricey, but I think it's a superior design to any tent I can think of for it's weight and function, and it's so encouraging that WE back their quality claims like this. ' on ya, Henry!
