Well, I have to travel with the boat quite a bit for racing, so I take the spin out of the snuffer each time I break it down. I leave it on during the regattas, but that's about it.

With the use I get out of the spin, I'm more likely to blow it out than have it come apart from UV exposure. I replace them about every 2 years, but by then they're as soft as bedsheets and about as useful...
