It does not disconnect and connects easily, but it eats up batteries within two weeks (kitchen spot) it's not worth it.

It simply doesn't perform the basic function it is intended for, which is to turn on and off a light! I have it connected to products from the same company. It connected easily, without any disconnections, but it doesn't have a good response when pressed. You have to press it 5-6 times to give a command... Sometimes it will register a double press... Very rarely does it work on the first try, and it is also very rare for it to register a second correct press within 15-20 seconds... The batteries didn't even last two months, and that's without any usage. The switch was simply connected to the hub... I would like to know if someone has used another switch, from a different company with the same features, without the need for grounding or neutral connection, and compatible with Sonoff products. I should note that countless tests were done on three of these switches! One single, one double, and one triple...
