Delivery about a month to Kharkov. Mist Express. No batteries included. The magnet holds well, though I have not bought batteries yet. It says that you only need alkaline. Looks like an interesting thing
Delivery 43 days from the moment of order. Packed in an envelope with a navel. Color as ordered. In the product description it is written to keep pressed about 5 seconds, then promoting, sealing. It is written that you need alkaline batteries (2 pieces finger AA, 1,5 V). I do not have batteries, I tried old batteries (PO1, 2 v), once something was welded, then nothing happened, then the batteries did not torture. Disassembled from Curiosity, the simplest scheme: 2 contacts, spring and heating wire. Bought for 46,72 rubles.
