Review: TOOO COOOL! - I am using it for an alarm system… I have wanted to try something like this for a long time… Make sure you print the information out and study it carefully. It is really a cool device and with some imagination you can do some really interesting things with it. Try not to let it intimidate you. I may add some more information at a later date if possible. I saw a review that said it wouldn’t work with iPhone… It works fine with iPhone just download the app.
Review: no warranty on product - this is the second i ordered in 9 months because the 1st only lasted 9 months there is not warranty of this product, there is not similar product for sale in market, so this is my last purchase, if this goes bad in a few months, i have to get a phone line in the house and buy a sensaphone or similar.

### ⭐⭐ Worked great for 2 months, then just quit
*by P***D on September 9, 2024*

I purchased this unit to convert my home alarm system from a landline to the cell network. The install went perfectly and the device worked well. I used the device successfully for two months. Then this device just stopped working. I emailed the company identified in the instructions asking for help but they never responded back.
