Hi @Sonnyb2 ,
I've never (to date.) prematurely lost a sensor. (I place mine inside the arm.)
However I have done buisiness with the guy that manufactures these & invested in a Miaomiao holder.
Like the ones below. It does the job, holds it in place without the need for double sided tape & easily removed from the sensor.
