We’ve fixed all of the disadvantages of battery toys, kept the advantages, and added some more! MR BOSS, from our game-changing BATTERY+ line, has the most powerful battery-operated motor on the market, takes standard or rechargeable batteries (and knows the difference between them), and can even be effectively upgraded to a rechargeable toy with the addition of a HYBRID KIT if you decide you want to make the switch. That’s right, we’ve invented patented new technology to change your relationship to your vibrator in ways you’ll love.
