The 'Oil Boing' series and 'Busty Swimsuit Racing' series have been criticized for having 'almost the same format' each time, leading to audience boredom. There have also been requests for more 'fully clothed' scenes and feedback on the way the swimsuits are removed. On the other hand, some believe that the presence of 15 popular busty actresses makes it worthwhile if there is a preferred actress, but otherwise, it is not considered a satisfying work.
