I am in the process of rolling a small IRA from NFCU into VG. As of last night, the money has disappeared from NFCU but not shown up in VG. I expect this will take another day or two. All in all, other than taking about a month, it's been a very easy process. Both NFCU and VG were very helpful in getting the money from one place to the other.
I've been very pleased with Vanguard's service every time I have called and will recommend them to anyone needing a simple, low fee investment account.
