Satisfyer One Night Stand
Womanizer The One
Both firms made horrible design that produces lot of unnecessary garbage. Stuff has battery holders, but it is all closed and user can't change them.
Not only this, but price is strange, as if you follow deals nice sucker with magnetic rechargeable cable from same Satisfyer brand will be only 10-30% more.
