k-redux-factory is a lib that aim to access your data as fast as possible.
By using selectors you are safe about our possible internal state restructurations.

For example, we move from keyValue like that:

• { keys: [], array: [], data: {}, initialized: false }
  to
• { data: [[]], initialized: false }

In this example if you didn't use our selectors, an upgrade of k-redux-factory could break your application. But if you used our selectors, it wouldn't.

Always prefers using lib API and not its internals, when you can!

Besides that I see these advantages:

1. We (k-redux-factory) can refactor our code without breaking your application (see previous comment)
2. You have a standard, always use selectors
3. You can move your factory around your store definition -> your containers will not have to be fixed
4. You can memoize selectors if you need to at some point

moreover, if you want to try k-ramel, you can access the state using k-redux-factory selectors in a quick way:

export default inject(store => ({
  users: store.data.users.get(),
})(Component)
