The alarm arrived quickly and in its original packaging. Unfortunately, I didn't know that the product required a remote control, since there is a package without a remote control, I assumed that it could be activated by a button or in the app. I ordered the product without a remote control, so it is worthless at the moment. Look carefully and order a product with a remote control.
