excellent so far (Review by Cam)

i rated it at a "4" because I've only used a half dozen times but it has been flawless.
Pro's: lots of room, breathed well in semi-humid conditions, packs up really small, waterproof, pole works great, cheap!
Con's: I see the 2.5 layer not breathing as well as its 3 layer counterparts once the cold weather camping starts up but cannot say for sure, almost too roomy/ or baggy.
