Delivered quickly (a couple of weeks) through tc sdek. The sensor of the new model, from the old one differs by the presence of a micro-switch under the panel for fastening and when the sensor shoots the alarm even if not on guard. Came with a battery. Attached without problems to the g18.

In astana delivered in three weeks. Took for $7.51. The door sensor works stably, the battery is included. Connected to the camera with built-in alarm. When connected, it recognized as two sensors, the first signal to open the door, the second signal to remove the sensor cover. The size for my door is too big, the ledge on the metal box of the door is narrow (see. Photo). It was necessary to take the last rounded model…
