Alzheimer Dementia Personal GPS Tracking Device - Pendant

I am very disappointed. After spending approximately $60 for this item, about $30 for shipping and waiting a very long time for it's arrival, I discovered that it is much larger than it appears in the picture (about twice the size). I had hoped to attach this device to my mother's Med ID bracelet but it is way too large, awkward and heavy. The worst part is that the sim card that is needed to make this item work is not even included. It is basically a very expensive, rather unattractive, empty shell. It is not clear from the description but in order to use this device you will need to not only purchase a sim card, but sign up for a service plan (they recommend T Mobile) and pay ongoing monthly fees. I really feel this all should have been made very clear in the description.

Did not want it but could not return to Camada because of lithium battery. Mail & UPS would nit mail it.

This product comes with no directions. I have no idea how to use it and as a pendant it is much too heavy for a frail person to wear.
