Familiarity: I've used it several times
I recently had the opportunity to use the NanoWave 55 which I just purchased this spring. I used it fro a week straight. It worked very well. The temps were a little warm, but I was comfortable up to about 60-65 at which point it was a little warm. The coldest it got was about 55 and I slept like a baby. I need to try it at the colder range of its rating to see how it does there before giving it the 5th star.
It does pack really small and the only complaint I have is I have not been able to get it back into the original compression sack. I have used a third party 10L compression sack instead.
