Cryolipolysis for already athletic males

I am heavily considering giving Cryolipolysis a try. The thing is i'm already quite lean as i workout a lot (11-12% bodyfat, 69kg, 179cm), but i think because i used to be quite chubby, i have 'bigger' fat cells around my lower back and lower abdomen. (Is it even true that fat cells can get 'big'?)
Given i have relatively narrow shoulders and naturally wider hips, i thought it might give me a much more aesthetic look. Are there any people that have a similar situation that tried it and had positive results?
I see mainly negative reviews of people being dissapointed but i also think most people don't really train and diet enough and expect a magical effect.
