Weak tape doesn't keep sensors attached

Overall, the system is working EXCEPT the double-sided tape used to attach the sensors is weak and begins to fail after a few months.  This has happened with both the systems we own.   A sensor fell off while we were gone from one  home and set off the motion detector, which in turn, set off the alarm, which in turn meant a call from SimpliSafe to the police, which in turn meant a police visit.  I suspect we will get a letter from the police dept.  In any case, I would strongly suggest SimpliSafe search for a better product to attach sensors.
