Even the old Intal Spininhalers look easier and they made a nice whizzing sound as the impeller span, but they had to be cleaned regularly as the powder stuck to the moving parts.
The other think I note was the nasal inhalers worked well up to the mid 1990s then became painful. If you have a sore nose duue to hay fever the last thing you want to do in inhale water up your nose. The old inhalers I now guesses used CFCs and were nice to use. The suggestion by my grandmother for hayfever was to inhale salted water up the nose, I only tried that once - it hurt.
