Ring Glass Break sensor false alarms

I believe I have found out why I'm getting false alarms from my (2nd) new Glass Break Sensor, and wonder if anyone else has encountered this.... I purchased my 1st sensor and it was giving permanently "tampered" alerts. I contacted Ring and they tested it remotely and confirmed it was faulty. I returned it to Amazon UK, and got an immediate next day replacement. The second one appeared to work ok, with no immediate problems, until the early hours of the morning when the Alarm sounded! On further inspection I believe that the problem lies with the small "post" that sits within the base of the unit. This "post" contacts with a microswitch in the main unit to send an "alarm alert" if the unit is tampered with. Has anyone else had similar problems with this product?
