Ondari lifting is expensive, but is it effective?

Recently, I came across reviews from people around me about Ondari Lifting, which claims to be virtually painless and highly effective relative to the pain. I became very interested when I heard that it uses ultrasonic waves to deliver heat deep into the skin for lifting.

However, since it is an expensive procedure, I am hesitant to make a reservation right away. Are there any actual users who have received the On-Da Lifting procedure at a dermatology clinic? I would like to hear your experiences regarding the definite advantages of On-Da Lifting compared to other procedures like Shurink or InMode.

I would appreciate raw, honest reviews and advice from those who purchased this product with their own money, rather than promotional posts. Thank you in advance for your valuable comments!
