Very good communication with the walking, fast shipping, good goods.
Complies with the description. Relatively easy Installation, mounted on my garage door and application on smartphone, works perfectly. The tablet app does not connect. The closing contactor did not work at all times but after moving a little the battery seems to work again properly. To see in time. Open dispute following malfunctioning of the opening sensor, I asked the seller to bring me a solution, either send me another sensor or a partial refund. The seller does not respond to my request. Not very serious
