couple things I don't like - sleeping bag slips all over it if you move around in your sleep alot. It's pretty thick so you slip off it and you notice that you slipped off it. Kinda stinks if everything is not perfectly flat. I like to sleep directly on the pad with the bag unzipped as more of a blanket - the tube construction makes this uncomfortable. and lastly, my dog popped my freinds Ether Thermo pad in it's 2nd season, so I question the durability.
Compared to my 10 year old old 3/4 length thermorest guidelite, I like the guidelite better...it's arguably more durable, lighter, flatter surface, lower, and sorta selfinflating
