I hear the Shrink Universe is really effective. How good is it?

I came across news about Shrink Universe, which is said to have less pain and a much faster procedure speed compared to the first generation Shrink.

I heard that dedicated modes, such as MP mode and a pen-type handpiece, have been added to deliver energy densely even to curved areas. However, I hesitated to make a decision because I was worried about potential side effects, such as the characteristic tingling pain of bone-piercing ultrasound lifting or post-procedure hollowing of the cheeks. Compared to existing procedures, is the pain with Shurink Universe really significantly reduced?

If anyone has personally received the Shurink Universe treatment at a dermatology clinic, I am curious to know which number of shots—300 or 500—you chose for the most satisfying contouring results!
