We've got around 5K on ours now with no problems.
However, you've got to realize these wheels are designed to be compartively light and aero. With that comes compromise. The spoke tension on the wheels is high, and that can lead to cracking around the rims.
I think if you use these, or other "race" wheels for everyday use, you've got to expect that they are going to need to be replaced or rebuilt from time to time, and factor that into the cost.
