Is the home-use Ulthera beauty device effective?

I was looking into home-use Ulthera lifting devices, and I found that they are incredibly expensive.

So, I became curious about whether beauty devices actually work. Unlike clinic procedures, since this is a product used at home, I want to know if I can feel any noticeable changes in elasticity or lifting. Will consistent use help refine my facial contours and improve skin elasticity? For those who have used it, please let me know how effective it was, as well as any side effects or precautions.

I want to hear real-life experiences regarding the effects of beauty devices.
