Query: Did not work at all

I changed the batteries (even though they give you new ones), used fresh fatty milk, and followed the instructions on the placement of the frother in the cup. Nothing. I kept it running for so long and still nothing. It made little bubbles and that was it. Very frustrating, went with the aeroccino because I've witnessed it's amazing frothing ability from a family member. Definitely way more expensive than the aerolatte but i guess i am desperate for good homemade foam.
