Perfect, I recommend. Product matching my expectations, easy to configure and place. I advise you to check with your operator for the micro sim as it may block alert receptions.
Material conforms to the description made on the site and receipt of the material as expected.

Order compliant, fast delivery
Very good alarm. The only small downside is the shape of the remote control whose buttons can be easily activated. I know you are working on it and it will be modified very soon, but I had bought 6 a month ago and it annoys me to buy 6 more.
Good service on the phone. Good product. Poorly designed manual.
Perfect!
