Like my friend would say, “I paid for the item, I want the full experience”

What brands and where you getting them from?

Both magsafe and wireless for me.

Lots of options. Some I can suggest are:

Spigen, ESR, JetTech, Zagg, Invishield.

I love their stuff.

You can enable family sharing on your iOS devices. Like one user mentioning of all the settings you have control of, the main account holder can approve purchases being made from the app store.

I would take her into the store and have her demo the iphone models to see which best suites her. A hands on experience with the product is always the best solution to see what suites them more comfortably.
