I used to, or maybe still, attach my wireless mic to the back of my battery, which is large enough to clear the backend of the camera.

Well I recently did a wedding outside, it was so hot that the glue that held my 'Frequency Sticker' on the back of the mic liquified and the mic went plummeting to the ground. And had it not been for the xlr cable that screws into the receiver, my mic would have probable been in a 100 pieces.

Everything is fine, although the frequency sticker doesn't stick back on, so I stuck the velcro straight to the receiver body.

It's a funny story now, not when it happened.
