Mine too, but this is how I fixed it:
I stopped shaking it like a maraka and now I see no evil & hear no evil!
(At least until I have a pair of Zeneses and feel like getting musical)
Patient - Doctor, doctor, it hurts when I do this! (imagine the patient moving their arm up and down)
Doctor - Well, then don't do that!
I found the medium switch tension setting ideal, but found getting consistent firing wore out my pinky. To reduce the switch throw distance I did add 1 washer (from the tool bag) under the screw head in the magnetic switch assembly (carefully do this, hold the whole button/cap together firmly, remove screw, add 1 washer (not 2 washers; the other is a spare), then screw it back together without letting go until tight.
I find the medium setting with 1 washer is like butter and 99% of the time I get effortless firing and find it to be the perfect throw distance when I squeeze the apv into my pinky.
The battery will still rattle, but I never hear it.
Enjoy your Zenesis, and congrats!
I had already added the washer, however I still need to press quite firmly to get a good contact every time and thought it may be the play. No more shaking it is then. Very Very exited to finally have it!
