- GKGP KieferJul 22, 20251.0Lack of transparency and failure to alert customers and clients earns this bank zero stars. According to their own customer support this bank was taken over by Old Second National Bank in July 2025. Compounding matters, the High Yield savings rate was reduced further without any notification. It went from 4.16% to 3.93% and I was not informed at all. Totally unacceptable. I quickly closed my account and transferred my money elsewhere for a better rate and service. Customer service also fails to respond by email now. Everything has to be done by an annoying phone call.
- CKCabana KeyMar 4, 20244.0Consistently high HYSA rates. ACH out-going transfers for newer accounts is restrictive. Otherwise, its a great place to park your money, and earn one of the highest yields around.
