Carrying an e-stim shock device

If you need to carry an e-stim device so a dom can shock you I have found that a microphone transmitter holder is perfect for this. I got one on Amazon that fits comfortably under my clothes around my waist or upper thigh and it fits a TENS unit or my E-stim Systems remote shock device perfectly. It makes the device much easier to wear and you don't have to fus with wires when you use the toilet. Plus it's very discreet as I can wear it under my boxers.

What are some of your experiences with wearing a remote e-stim device? I have read some stories on here with people wearing remote vibrators or remove e-stim devices with a partner holding the remote. I would love to have a partner in charge of the remote and able to shock me when I miss-behave but I have never had the opportunity.
