Messenger C1 Off-Grid GPS Communicator and Tracker without Monthly Fee and Cell Signal | Connect with Phone via Bluetooth for Outdoor Activities

It's fairly easy to install and to use. The two devices were shipped to me in a couple of days. Pretty good battery life. I left the devices on for 3 days and they still have 40% more juice left. Very impressive. I could monitor the battery level through the app. I used it in Airplane mode and with WiFi disabling. I still could use text and audio with my friend in hiking with a really long distance. It's a very cool gadget to have.

This device works great and is pretty easy to use. On my second hunting season using them. Only the phone app drains my phone battery like nothing i have ever seen. Lasts 1/2 day at most. The device [Radacat] battery lasts a long time.

Doesn’t work ask promoted. Couldn’t return it either.

Instructions are printed so small difficult to understand or execute. Obvious someone not fluent in English wrote them. Has absolutely no value to me and a total waste of money!

The product is well packaged and shipped. It is very easy to install and setup from my iOS devices. You can easily setup a group. After we turned on air-mode from iOS devices, we still can leave text or audio messages to each other from fairly long distance. This is a really useful gadget to have when you go out for hiking, especially to the places where no cellular signal is available.

Works well, though the texting is a little unreliable. But tracks well.

Works well, drove it around our hilly sixty acres and it never did not fail to send a message, slowed down some to where it took a few seconds longer sitting behind some hills but the messages all went through. Only issue was I had to restart the app a few times when it would fall off the dashboard. I’m buying another.

product seems great in concept but the execution left much to be desired. I attempted several times to get this to function properly and eventually gave up and returned it.
