Our two cats have this same hammock tree and over the last few years, have used it daily and it was definitely showing its wear. They love the crinkley sound in the new hammock (wasnt in the older version) and have been playing and sleeping on it and in it ever since it arrived.  One note if caution - be careful of the hanging toy balls. One of our cats batted one on the older model and it wrapped around her paw and she collapsed the whole cat tree while thing trying to get free. We untied them on the new one right away to avoid any accidents.
