so funny u people - u keep asking question after question ... thinking you are going to get answered - but where do you ever see an answer ???? At least its better than the morons who give their e-mail address, and say crap like "u r so hot baby, email me sum time ok, cos I luv u so much". Please spare up. If any guy here thinks they can match these machines in intensity orlongevity, u are either living in la la land (don't worry, its a big town) or you should be in the porn industry. I agree with the low video quality comment.
