Well, not exactly.
My son's girlfriend, about 30, says "What's that contraption on your counter?" I quickly explain, ask her if she likes orange soda, she says yes, she loves orange, I pull cold bottle out of fridge, I make a bottle, she tastes and the look on her face when she says it tastes great sells another million machines.
The above took less than 60 seconds and could probably be fit into 30 including her saying "We need to get one of those."
I did the same thing with a guy on Thursday who was fixing some window blinds in our house.......he saw a co2 bottle and asked about it .....I took him into the kitchen filled a bottle ....carbonated it and put root beer in and got a glass of ice and had him taste it......loved it and was glad there was no aspartame in it.....walked out of the house saying he was going to buy one at BBBY.....works every time
