Cmonsterwrote a review of Big Agnes Insulated Air Core Sleeping Pad - Rectangular on June 26, 2013
Familiarity: I've put it through the wringer
I hate this sleeping pad. I've had 2 of them (I thought my first one might have been a dud). My fiance had one a little while ago also.
Every one failed and failed quickly from a valve issue.
Now, granted, ever air pad is a ticking time bomb, but this one especially. Unless there has been a massive valve redesign project, I'd be wary.
I've had a much better experience with the Thermarest NeoAir trekker. It failed too, but after a couple of years of frequent use instead of a couple weeks/months.
