I have 2 3rds being built with them right now. So I will let you know in a few weeks...
When I searched all I could find negative was the video of the ARB guys breaking one. But I guess that was a prototype, who knows. For me right now it boils down to price and I couldnt swing the ARBs this time around.
I dont think I will have any issues, I am only running 35's and I am not "hardcore".
