discreat ads?

So I reallt need some sort of discreet ads I can wear under my clothes at work. Do you have an suggestions?

Types “ads” into the search function. There is a lot of information about them.

I already have the phallosan forte a d I’ve been having great results with it. It is a little bulky and tension clip creaks and goals a bit as I walk and move so it isn’t exactly discreet. I was thinking of maybe getting the penimaster pro belt system instead. Is there anyone with experience using both as an ads? And which is more discreet and easier to wear during a day at work?
