Very happy so far
I opened a Junior ISA for my two kids. Needed to speak with Scottish Friendly twice on the phone (once before opening the accounts and once after). Both times the phone was answered quickly, and they were very helpful.
Website is decent. Their iOS app is also decent, which is surprising because I hadn't heard of Scottish Friendly before, and incorrectly assumed the app would be awful.
Cashback is tracked but not paid yet. I'm very happy, and would recommend.
