2 Lundurg chair alarm pads and monitor
paired with one bed alarm pad.
These pads might have a year left on their internal batteries. The monitor batteries are standard and changeable.
I think it's best to gift these together as I only have one monitor. On the other hand, the monitors are easy to get on Amazon and if someone only wants one of the alarm pads I can provide the Amazon Product info for the company.
The pads helped me to know when my Dad had gotten up. Does NOT prevent getting out of a chair or bed. They do tell a caregiver someone is up.
