What do you think of the Tyrepal tyre pressure monitor?

I have been considering the possible merit of using TyrePal. My concern is that the device that fits to the tyre valve and must hold the valve open to be able to see the pressure. Without TyrePal there is both valve and cap keeping the air in. I accept that in event of puncture the device will see the pressure reduction but am concerned that the risk of leak from the cap with the valve held open is increased. Any thoughts?
