M521 Wireless Smart Home Security Welcome Chime Kit Door Bell Alarm Led Light Button Battery

Well packed, looks decent. For me, the pluses that in the "button" is already a battery, and the "meat" works from the network. Three Volume, a bunch of melodies, with illumination did not understand, but flashing in different colors when press the button. In the set of self-tapping screws and double-sided tape for the button. It's good that the plastic is matte, there are no prints

A good call, there are standard tunes, and there are also original, melodic and cheerful. Batteries went in the kit, but get them to replace that other pleasure... I do not really imagine how to change when the button will hang, apparently, I will have to shoot the button. And yes, there is memory, if you turn it off, the settings will not close

Prompt delivery to Israel in 8 days. Nice call. I can choose many tunes. Even the Russians. But there is a block that is inserted into the partition. I mean, we need a place to do that. The melody comes from it. Perhaps someone will be uncomfortable. It is not small, but from the floor of the palm. I adjusted with bought a tee.

Handy wireless doorbell, I use it on the outside with a visor. I have 30 meters away the receiver's doorbell, with 2 intermediate walls and it works beautifully. Different shades and length of light and volume, everything is customizable. A perfect and economical solution. Highly recommended.

The goods is according to the description Everything works (came with a battery). Melodies have not yet set up, works for 15 meters, then I have not tried it yet. But I think (judging by the reviews) will get to 25-30. Cool and most importantly convenient. Seller respect Recommend
