• The 'soft ball' may NOT feel as soft as users expected. In cold room the soft balls feel almost as strong as the hard ones because the rubber of both becomes much solid. But under warm room temperature, the soft balls feel soft due to less rubber density compared to hard balls. However, the density of soft balls is just little less than hard ones in order to stay functional, thus users may not feel big difference between the soft balls and hard ones in terms of levels of stimulation. Please keep this into account before placing orders.
