Good and works as expected
Just the same as the original one I bought with the kit. Had to bind it to my system, the instructions I already had made quite easy work of that, basically switching the main unit on and off a few times till the right beep sequence was emitted One thing that bugged me with the original one was how quick the battery ran out, then I tried to fit a larger rechargeable battery of the same voltage but it blew the door sensor, that's why I've had to buy this one ! Instead this time I've fitted an on off switch, successfully , much better now ! Eco friendly and pocket friendly

Works good
I've fitted this wireless alarm sensor to the door. I've connected the alarm sensor wirelessly to GSM alarm. It worked good, and had no problems setting it up.

Good item
Bought 11 pieces in addition to the Kerui home alarm system set. Total 21 pieces as part of the home alarm system, none defective. Able to trigger the alarm as far as 20m from control panel (maximum distance in my house) with 2 stone walls in between.

Fairly easy to set up
Got this to add to my system as the alarm only came with two contacts and my shed needed three to fully protect. No instructions came with it but the alarm instructions did kind of explain how to pair it. After a few tries I got it sorted and works fine.

Works fine but flimsy
Works fine, consistently and with a good range given the extendable antenna. However, plastic case and back doors are quite flimsy.
