    I order the alarm is not the first time, the delivery is fast, the track is tracked, in general the seller does not deceive. Before that i ordered with delivery from russia-everything came in factory boxes and with batteries. Now i ordered from Warehouse-everything in bags, batteries are almost nowhere. There are certain difficulties in setting up the entire complex, last time everything turned out. Now order other alarm and much more extras. Devices, i’ll see how it all makes friends and complement the feedback.
