It wasn't until I tried to cancel the service and transfer it to another family member was I advised that the unit I have is "outdated and not worth returning" to them. Also, I was told when the service was started, 6 years ago, that Mom would OWN the unit after the 3 years of monthly payments & the family could transfer the service to someone else after she passed away, without it having to be immediate, lie, lie, and lie.
I'd like to warn anyone that has had a unit for over 6 months to call Life Alert [protected]) and request a free upgrade, ASAP. Be patient because you may be transferred several times, but the only way you will get an upgrade on your "rental unit" is to ask for it.
You would think after paying so much money for the unit and the service monthly, under contract, they would be required to advise the consumer of technology upgrades necessary to maximize the service to them, but no, they did/do not.
I also had to fight with them about getting a credit back for services they charged after Mom's death. They were very unsympathetic, cold, and uncooperative until I insisted they give me the information I required to get a credit. Purchase with caution!
