If you're going to wear it on your belt, I recommend taping the battery cover on for when it falls off.

Original batteries are still good and the range is outstanding

We test it from the furthest distance to make sure the batteries are still fresh

The call buttons are mounted to walls, so no loose battery issues.

We tried changing batteries and still wouldn't work.

put the batteries in and your good to go

I tried fresh batteries, but it's still dead

Opened it up and the battery it came with had leaked and even with a new battery will not work.

I put in new batteries and test it and it works

The battery moves around inside the case and the alarm will not work until you take off the cover and readjust it

As the battery gets weak the range decreases so be aware that its not 100% reliable

The customer service representative recommended the 433-EC, the receiver uses 3 C batteries, but also comes with an ac adapter; and you can add up to 5 buttons, however it will keep sounding until you turn it off at the receiver.

Tried changing the batteries, made sure the call button was being used correctly and had a good battery in it, yet the page function failed

I tried fresh batteries, but it's still dead

I would give a higher rating except for the missing batteries.

I replaced the batteries; no luck.

definitely a great product for families taking care of their loved ones.we have been using this basic system for 4 months now, batteries are still working, pager is still working, call buttons still working just fine

I would hate the battery to be dead when the emergency presents itself.

The 12 volt 21/23 batteries that go in the call buttons were dead on arrival

I purchased this for a senior hospice patient; out of the blue it quit working, tried changing batteries and still doesn't work

The batteries were still strong, but pagers wouldn't sound.

one battery came dead

Amazon Warehouse deal was missing the batteries for the call buttons but those are standard garage door opeber 12v so easily obtained.

Its hard to tell when the battery is dead, because it gradually loses sound, which has caused lots of accidents in my house

Good price but battery can come loose inside easy.

, easy batteries' replacement if you follow the directions, good price

It is loud and works any where inside as well as

I can hear it anywhere in the house as well as on the deck

It's been used and worked exactly as it was supposed to.

Transmission is between the button and receiver, does not rely on some outside cellular or wifi service, works exactly as we need it to, and is reliable and simple.
