If you have not yet tried that interactive thingie, I suggest you go for auto mode once you are in and get the password from the model. Using the manual option is a chore lol. It seems to have a mind of its own while you use your right hand, the left or both to furiously move the mouse up & down Rather, why not choose auto, set a desired speed, and keep your hands free to type & engage with the model more or for other stuff Quote

Another thing to note here - you may tip and ask the model to switch on the machine for you BEFORE you go for a private, to check if it's working fine. I strongly suggest you verify. Most models seem to assume it works fine and then once in private, you may end up sitting like a duck and just blinking eyes for several minutes while she does this and that to try switching it on and then finally say to you she didn't know she got disconnected from server -_- Quote

Sex machines are more a distraction . Several models hurt from them . High cost for the machines . Spread disease when used in studios from multiple models without proper cleaning .

Yup distraction , seeing the model get hurt , and getting a disease from bl00d or sexual fluids from improperly cleaned .
Not all things can be cleaned - plastic and rubber toys should NEVER be shared . Quote
