My NeoAir had a leak right out of the store, very slow leak. Sadly didn't test before heading out for a multiday trip and always had to refill the matress in the middle of the night at least once.

Exchanged it for an Exped SynMat UL 7 which was similar weight but felt more durable than the original yellow neoair i had. Just used the Exped for the first time fo a week of camp and it was really nice.
