Hm, that's strange with the pressure. Because I can use light pressure and still the cups will stay on. Do you press down the green little thing on the cups to seal the vacuum?

To release the pressure you just need to pull the little green thing (don't know how to call it, lol).

Omg, no. I never knew you had to press down on the green little thing. I know that you have turn it to release pressure. I'll have to try it tonight. Thank you.
