Great call, lots of tunes. Through several walls plugs without problems.

15 Jun 2021

Product arrived as advertised! Works perfectly!

15 Jun 2021

Nice call! Made qualitatively, the button seems to me to miss water, it is necessary to hang under the canopy. the battery in the button was. The sound is loud at the base, the tunes change. To Moscow, the parcel was two weeks old. the whole box, was packed in a bubble film. I definitely recommend the store! Thank you!

The parcel was sent by mail of Russia. Quickly enough from China to St. Petersburg came in 11 days. Packed perfectly. Goods and a box without mechanical damage. Works well. The volume is high, adjustable. Many melodies can be chosen for every taste. Excellent buttons overcome obstacles from the walls. The corridor is L-shaped and the button catches the signal. Excellent solution, installation without wires. That's how much the factory battery is not yet known (in the kit for the buttons were batteries)
