Delivery to m. o. It took 11 days. Everything works great. I took no, I.E. If the magnet is not carried-the chain is closed, if the magnet is carried-opened.

Ordered two. The goods came, but alas one of them did not work properly. But the seller without problems agreed to return the money for one piece. And I can if I need it, just order it again. Seller recommend!)
Can who tried to change the magnet for more powerful, to increase the sensing distance? Do you think you can increase the distance to 2-3 cm?
I didn't get sensors. But if you follow the laws of physics, then the strengthening of the magnet should lead to the operation of gericon at a greater distance
