Windows 8.1 phone Dev preview Lumia 521 update: Any problems?

I want to update to 8.1. But after reading the forums there seems to be plenty of trouble. Any luck with the 521?:straight:

I'm kind of late to the party. I ran in to a few issues at first but doing a hard reset did the trick. My phone has been running smoothly ever since.
