Muito boa essa campainha, vou testar a distância mais longe pra ver se funciona bem
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.
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
As always, the product is excellent, I buy not for the first time, the quality of plastic is very good, the call button goes with the battery, I definitely recommend it, thank you you
Rings, melodies a lot, the button is offered to stick with bolts
Very useful thing. You can connect to any free outlet.
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
The call is super, no comparison does not go with the shit that is sold in Minsk in the markets. The melodies are very beautiful.
Arrived very quickly. Efficient, congratulations. The product is as the description, found very beautiful. Tested the buzzer sound and liked! Has a unique quality, now will test with a certain distance. Believe that will work far from home. Thank you!
