Synchrony IRA CD 5.1%

Synchrony is offering an IRA 12 month CD at 5.1%.

I would do a rollover from Vanguard. Currently earning 3.58% in the VG Federal Money Market account. So a bump of 1.5% essentially.

My concern is what can I do when the CD matures. Assuming Synchrony is then offering low rates, I would need to roll it over back to Vanguard most likely.

Has anyone done this? I just went though the rollover gauntlet with some 403B annuities for my SO. Corebridge were total A-holes. Western National Life were bad, but at least they did what they should do. Both of them drag their feet if it earns them a few pennies on the money.

My concern is Synchrony takes the full 60 days to roll over the funds when I want to take them out after the CD matures. That would cost me about 0.6%, which means instead of earning 1.5% more I'm now earning 0.9% more.

I think I'm talking myself out of this.

Anybody have any experience with this situation?

Vanguard has been great and honest. Corebridge and Western National Life not so much. Will Synchrony be more like Vanguard or Corebridge?

Thanks for sharing your wisdom.
