"I was at work at lunch with my co-workers, and suddenly I was zapped!! The unit is quite and discreet. Thank God! But I loved it. I never know when Betty is going to do this, so I am always anticipating, and never disappointed as it happens frequently. I love this training, and will never quit. I have seen other dommes charge much more for similar type of training, but this hands down the best deal I have found like this! Betty is very personal with her messages to me too. Thank you Betty!"
