Made simultaneously two orders identical PIR sensors-here and in another store (there was $0,8 cheaper). As a result, the parcel from another store came from China a little earlier (although ordered from the Russian Federation) in some 'left' box, there were 3 AA bars in the kit, but forgot to put the mounting bracket with dowels and screws. Now it is not known to send the missing or not, as the store hinted that such small shipments are often lost. The same sensor is truly Kerui (unlike the first one), in a branded box, in full configuration, but without batteries. I advise you to buy here.
