I got this specific doorbell as a replacement for a Cacazi (A8BB 11) that was given elsewhere. It had the same logic, a receiver with two transmitters (I bought two pieces), but its range was 300m.

So, regarding the Sencor, which will soon be replaced:

- in terms of appearance, it looks exactly like in the photos. Quite beautiful, I would say, and the blue color makes it more noticeable. At the bottom of the switch, there is space to put your name on a piece of paper.

- the button, the blue part, is made of rubber, and the switch to activate the doorbell is in the center of it. This means that if you press the switch anywhere except the center, the doorbell won't ring, and you won't feel that click of the switch. There should be a hard plastic underneath the rubber that would cover the entire surface so that pressing it anywhere would give a command to the doorbell... But these are details, especially for this price... Of course, when the switch is pressed, a blue LED lights up...

- Sounds... It does have 48 melodies, which I didn't count, but there were many. The people who installed them had all the cordless phones in their homes from 1995 onwards. Panasonic, Siemens, and Philips, I suppose, since the melodies are the same. You press the doorbell, and you hear Beethoven's 9th Symphony. The whole thing. So, you go to the door to open it, come back, and the doorbell is still ringing. If you're lucky enough to have one of the above-mentioned phones, you can set the same sound just to annoy the others in the house. The sound rings, and you don't know where it's coming from. Should I pick up the phone or go to the door? The sounds should be the usual ones for a doorbell, like 2 or 3. I won't check now because the sounds go in a loop. I should mention that the Cacazi had the same logic, but at least it had more sounds of the classic doorbell. The volume covers all preferences, but the speaker is not as good as in the Cacazi, as it rattles at high volumes.

- Range. This is where it disappointed me. It says 150m in an open space without obstacles. So, if you have a garden with a distance of 150m, you're okay. Of course, by the time you go to open the door, the person who rang the bell has probably already left. And if something gets in between, the range drops dramatically. For example, in the one I installed, the straight distance is 10 meters. There are two normal walls in between, while the button is on a pillar. So, if I move the receiver one meter, the doorbell goes out of range. The other button is at an angle at a distance of about 15 meters. No discussion about that. I'll have to take the receiver outside the house so that the person ringing the bell can hear it and open the door themselves. Thank you, welcome...

Overall, good construction, it seems to be quite waterproof, so the IP44 rating should apply, but the range disappointed us...

Update 07/10/21

Well, it seems that the issue with the range has been resolved. Because I was concerned about its behavior, I opened the receiver to see if there was something to adjust. So, I removed the 2 screws of the plastic cover and then the other 2 screws that hold the circuit board. There is a potentiometer there, which I turned half a turn clockwise. The doorbell now works with both transmitters in positions where they didn't work before!
