When attaching the tail part to the plug (to make connection between batteries and receiver) DO NOT twist hard. The thread is so fragile it splits. Infact don't even play with it when its in because you might break it.
Perfect stimulation, simple easy to use, fits snugly, OMG it amazing taken our play to a whole new level and the control gives my partner more ability to play the night away thank you ATMS you are amazing!!!
