Ordered this product to help with my bedridden husband calling me. I was very pleased with the product when I received it. The directions were straight forward and easy to understand. It was very easy to synchronize the receiver with the SOS button. The volume control as well as the choice of ring tones made it nice to personalize. The button was upstairs away from the receiver but it operated well over the distance. The SOS button is very easy for him to use,( And use it well he does!) It is also a bonus to have a regular doorbell setup to use if we needed it in the future. Met our needs very well.
