Got quickly for from Russia. To the door by courier-convenient. Whole. White looks inexpensive, but not pretentious. The door button is small, in the film. On the back of the paper is inserted-apparently, closes the contact of the battery inside. Insert the unit into the outlet-sends a signal. Included fastening and Velcro. Then I’ll install it at home.
Klemens Totleben –
Sent was not immediately, but the delivery is only three days by courier home. Call and two buttons included. Did not immediately turn on the call, if someone has the same problem you need to turn on the call to the network, then press simultaneously the button to select the melody and volume on the call, release, then press the call button, the button and the call will establish contact and everything is ready) the sound is good, loud, the melody can also be selected to taste. In general, we are very satisfied. Thank you seller and shipping service.
Verline Cordon –
Everything is very easy to use, the call is inserted into the outlet, the button itself is powered by a battery (A23 12 V) included (well, at least I already stood in the button). The touch button, everything looks beautiful, when pressed, a nice blue backlight. On the very block of the call there are 3 buttons, the central answer to the volume of the call (only 4 volume levels), the maximum volume is excellent, well, and the melody change buttons +/-, everything is very simple, when pressed, there is a change of melodies, only 32 different melodies, everyone will find a melody to the liking. To work still need to tie the button to each of the blocks of the call, it is easy, press simultaneously the Button + and the button in the middle and you entered the pairing mode, bring the button closer and press the sensor and then just press the central button, that’s all. Repeat these actions and with the second block of the call, now when you press the button they will call at the same time, each block can set a separate melody.

Greta quality, super fast delivery, to Lithuania per 7 days.
Ira Forster –
I put such an assessment in absentia, and only because everything works in principle and trust this seller, as I already bought in this store and everything was norms. But there are questions:
1 package does not match the description at all.
2 There are no batteries in the kit, and judging by the reviews should be.
3 and one button is not sealed, it can be seen that why it was opened not once, there are scratches and does not close tightly.
And so in principle all the rules. I recommend. The seller answers. Track was tracked to the Post Office. It’s been three weeks.
