=== The 1byone radio Portable doorbell ===
The wireless doorbell is completely black, which looks really classy. She makes a very high-quality Optical impression and was also processed very clean. Firstly, here you have the receiver with 230 V. This is the front all the way down the LED display and above the speaker. On the back is the power connection, ie the plug for the power socket. On the side, there are three different buttons and a sliding switch. Firstly, here you have the Automatic Code, the melody selection, the volume and the ringing and flashing selection switch.
The receiver battery operated looks almost exactly like this. Front is also here the LED display and above the speakers. This receiver has the buttons and the slider, however, not on the side, but the back of the back, but with the same functions. Here you have also the battery compartment where you must insert 2 AA batteries. The cover is easy to open and easy to install the batteries.
And then you still have the transmitter. This is really nice small and narrow. Here you have below a transparent cover under which you can attach a name tag. Very useful when several parties live in the house and to install the wireless doorbell outside. Above this is the bell button in white and this is also quite large. They can be operated easily and responded immediately to pressure. When Push is always a "cracking" sound.
You can mount the transmitter either with screws on the wall, which are also, together with the dowels included here or attach with double-sided tape. Even that is not on this list, and we have opted for the tape. This works very well and keeps amazingly well without falling. The bells are in the supply already in a coupled state and can be used immediately.
Is now at the door the bell button, the transmitter sends a signal to the receiver and it is activated and will ring. I have several ways of setting here. I can adjust the ringing of the receiver and simultaneously flashes that he only blinks or just ringing. In the volume I have three stages, but they are really loud enough so you can not hear the ringing. If you have the setting flashing with activated lights up when it rings, a blue LED light. This is not to be overlooked.
Overall, I can choose between 36 melodies here. Because of course you have the normal Ding Dong and also standard on classical music. Many of the tunes you immediately recognize it and are really pleasant tones. Beautiful are the two receivers. One can put in any space in the socket and take the battery operated sometimes with access to the terrace. So you can hear in any case the ring and I am no longer in front of a locked door. With all the walls of the front door to the terrace there are good 60-70 meters with my mother. The range is so really class and it works flawlessly with no failures.
At the processing I have no defects found. Although dominated plastic, but the workmanship is good and the design is successful. By the IP44 standard, the transmitter is to use also splash-proof and suitable for outside.
=== === My conclusion
I am very excited about this radio doorbell. On the one hand you have two receivers, one of which can be inserted into the socket and take the other with sometimes on the terrace, the range is class and even through thick walls is no problem, you have different ring tones to choose from and the operation is very simple. From me, there are five star and a buy recommendation.
