I was tempted by the very different prices and received In-Mode Shrink from the factory model a few times, but I regretted buying it from a famous place for this much money, so I regretted trying Ulthermagi once . My cheeks were dented and there was no effect at all. I also tried Oligio, but he asked me if it hurts and said he would try it himself if it didn't hurt. There was even a director who talked about it.
