I've had the same set of string leeches for a year and a half and they are just fine. And I shoot year round. Cat whiskers are fine too, I had them previously. I switched to all SIMS products. Leeches, Limbsavers, and Stabilizer, and my bow is way quieter, and there is a lot less vibration. I am a big proponent of all the SIMS products. If you buy some leeches that have been on a rack for a long time, or if you leave them out in the sunlight, they will become brittle and tear up easily. If you keep your bow in a case when not in use (like me) they should last you two or three seasons easily.
