The instant model we bought is Viva. The description lists Viva as one of the models this device fits. However, the diverter is too large to fit snugly against the vapor release valve. When the pressure was released from the overpressure valve for the first time, the switch was torn off. I had to use a zip tie to attach it to the valve so it would vent the vapor properly. I'm sure the switching valve would work fine on a different model, but not the smooth-sided drain valve on the Instant Pot Viva model we have.
