I bought a pair of the simms Freestones in October and had both boots develop holes in them by middle of November. I sent them in at the end of November for repair as they have 1 year warrenty on repairs. I just heard back from them last week. " your waders have reached end of life and we will not be repairing them" I'm on my 4th pair of simms waders in 4 and a half years. It's safe to say I will not be going with them going forward.
On another note simms boots are amazing. I just bought a new pair this year and my old pair still work perfectly fine just a little too much wear on the felt soles. But 5 years of use is amazing to me especially when I fish 4-7 days a week from September to March.
I can't speak about the end of life comments, but Simms and the local retailer you bought them from should provide a way to honour the warranty. Assuming you bought them new, you shouldn't be out what you paid for them.
That said, if your going through a pair of waders a year on average, you might want to get a higher end model that can endure whatever you're throwing at it. To me, it's like using a 1/2 ton truck to do a one tons job. It might get it done for a while, but it won't last very long. Freestones are great value for the price point, but they are value. Of all the models in the Simms lineup, they are the second least expensive model which means it has less material and less production costs than higher end models like the G3 Guide or the G4. I personally have the G4 (non zip front) and have put 30 to 40 river days on a season and I don't experience any quality or workmanship issues. Now, there's been a time or two on a mossy rock or ice where I've slipped and eaten cupcakes and damaged the waders, but that's my own doing.
