The waspinator has anyone had any success

Hi
I have inherited fruit trees on my plot plus 2 walk in fruit cages. I have a very big phobia on wasps, I just cannot deal with them it's quite embarrassing when I love gardening and fruit. I have been reading about the waspinator, and was wondering if they are worth the money and keep them away. I was thinking of hanging one from each fruit cage roof and a couple in the fruit trees at the other end of the plot. Thanks in advance.
