Query: My girlfriend says it's the best she ever used

we use this during our course of love making. The first one she owned lasted almost 8 years with regular use so we bought another. She says she has used many vibrators over the years and nothing compares to the eroscillator. Extremely intense orgasms.She sometimes uses it solo for a quickie. I can tell it delivers intense orgasms for her. Its use has become a routine.
