Home8 Wireless Security Alarm System (4 Piece Kit) Smart Collaborative, 2X Door Sensors, 1x Arm/Disarm/Panic Keyfob Remote, 1x Smart Hub, Alexa Integration

I have been looking for an affordable home security package for a long time, a friend recommended this to me. For less than 50 bucks it comes with two door sensors, and a remote key chain, it is for sure a good deal! Set up is minimal, and completely effortless. The manual is clean and clear. Using it a few days, i would say this product is solid and durable, and the app tells me every time the door opens. I can get alert no matter where i am.One thing impresses me is the signal range of this little key chain, i am able to get use it on second floor even i put the security hub on the first floor. Seriously you cant go wrong with this product, for me hands down the best investment in 2019!
