Query: no jiggler

I had a wonderful pressure cooker. Nothing was wrong with it, it was just old, but I replaced it with this model and I can't for the life of me cook a decent meal in it. I was used to the rhythmic shush-shush-shushing of the jiggler on top that my old one had- told me when to turn it down/up... start my timer. This one doesn't shush. I hate it.
