These hammocks rock! Bottom line. They are light, easy to transport, easy to hang, and even easier to relax in. I haven't had mine for more than a month, but I can tell that it is built like a tank (a very light weight, easy on your back, tank).
My only recommendation would be to buy some light weight climbing grade caribeaners. The stock caribeaners are very heavy and add a lot of unnecessary weight.
Also note that even though this is labeled the double nest I would plan on getting two people into it, especially for sleeping, it'd be pretty tight and uncomfortable. I do recommend the double over the single as the extra room is much appreciated.
