Is Ultherapy a procedure that offers effectiveness and satisfaction commensurate with its price?

I am considering Ulthera treatment because of concerns regarding facial elasticity.

I've seen a lot of reviews saying it works well, but the price isn't cheap, so I couldn't easily make a decision.
For those who have received the procedure, are you satisfied enough to feel the cost was worth it?
I am curious how many sessions were needed to notice improvements in facial contours or elasticity.
I would also like to know when you started feeling the effects and how long the results lasted.
Was the pain tolerable? Will there be any swelling or significant inconvenience in daily life after the procedure?
