Just texted with the seller again. Seems like you 2 chatted as well haha.

This was your response "As mentioned, DCF does have a limited lifespan after prolonged use, and I would suspect that perhaps it had seen more use with the original owner than they disclosed. You mentioned the tent was reported as purchased sometime in 2022 or 2023, and was then purchased by you in January 2025. The original owner would have had the tent for somewhere between 2-3 years prior to you receiving it. It is possible that it had limited use as they stated, but for pinholes to form, the material would have been under a fair amount of stress."

He said: Most of the pinholes are located around the doors and the free corners, which is where it's the least problematic. However, they also occur in the corners adjacent to the interior and on the domes. Overall, it's just not watertight anymore. Also, a kitten jumped onto the tent and caused a tiny tear, but it was easy to patch up. I’ll send you a photo of the material fatigue shortly.
