Note
1. Our product needs to be used with a receiver, unless you have previously purchased our product and need to purchase additional accessories, otherwise purchasing a transmitter or receiver separately will not work.
2. Our product uses RF433 communication, but it cannot be mixed with other RF433 products because in addition to frequency, it also needs to meet the requirements of decoding and coding speed.
3.Due to the significant shielding effect of metal on wireless signals, please do not attach the transmitter to metal doors such as iron doors, anti-theft doors, fire doors, etc. In addition, the receiver should not be obstructed by metal plates.
If you find that the response distance is too close, please be sure to check if there is any metal affecting the signal transmission and reception of the product.
FAQ:
Do I need to pair the product after receiving it?
If you purchase a complete set of products, they will be matched correctly at the factory. You only need to connect the receiver to the power and it can be used.
Is it possible to add accessories later after purchasing the product?
If the purchased products are all of our kind, they can be equipped with accessories at any time, just pair them after receiving the goods.
Why can’t your product be mixed with products of the same frequency on the market?
This is indeed difficult to mix for several reasons. Firstly, other people’s products may be encrypted and not allowed to be mixed with products from other manufacturers; Secondly, although they are all products with the same frequency, other factors need to be considered, such as decoding and the speed of sending data packets.

Shopper –
functions perfectly! great color
V***t –
The doorbell works, the volume is sufficient. Only the reach is definitely shorter than declared. For me, it’s like this: 15m. But it’s through two thick aluminum walls and mainly it’s enough for me, so satisfied.
M***z –
It sounds very loud and has many sound options, definitely recommended.

It works very well, it sounds loud even though it’s almost 30 meters away. Additionally, the doorbell doesn’t need batteries. I recommend it.

Have had this for a couple of weeks i think and it works fine. I didn’t screw it to the door frame but used the double sided tape

Excellent doorbell, a wide variety of sounds and they are heard with great quality, loud without losing sound quality. Additionally, it connects over 100 meters away. I have already tested it. Buy with confidence, I highly recommend the seller. They arrived at my home in 9 days. We will see how long they last. They are made of good material. Excellent packaging.

So far working perfectly and from a good distance.
R***z –
Delivery time —> Germany = 8 days – that’s good; packed in a consolidated shipment – extra packed in a box and thus well protected – very good! The product itself works amazingly well and reliably – plug the receiver into the socket and everything is ready to go and completely sufficient for my route of approx. 40m and still through the wall – however – as it also states in the description – you are not allowed to attach the transmitter to a metal pole – this significantly reduces the range – I am very satisfied, never buying batteries again – I recommend the product and the seller.
Shopper –
It worked exactly as the seller described.
The melodies aren’t the most musical or subtle, but this thing can be configured to make a loud noises.
