I’ve had it for two months now
It works perfectly well , only put batteries stuck one piece outside and the other has a clip so you can adjust it in any room of the house . The distance between both devices is about 8 metres . lol

Excellent doorbell in terms of wireless communication, sounds, and battery. I would buy it again if it weren't so easy to steal. (even when screwed in)

At first, it seemed like a good purchase. The distance where I placed it was short (about 3-4 meters with only the balcony door as an obstacle) and it had good response. However, while it worked normally at first, after about 2 months, every time we pressed it, it rang both for us and for the neighbor who also has a wireless doorbell, which did not happen in the beginning.

Very good with great range, immediate response to the press even through many walls and floors. Now, as for its waterproofing, I am a bit skeptical; the front button is fine but at the back, at the opening, there is no gasket, so it is better not to install it on a wall exposed to rain. If it gets 2-3 drops, it's not a problem, but if water runs down the wall, it will get inside

Good range, variety of sounds, easy installation. It remains to be seen how durable it is in weather conditions.

My only complaint is that although it is waterproof, the outer button gets wet relatively easily if it rains a little sideways, and the paper inside got wet almost immediately, resulting in the name not being visible. I had to make a laminated one and stick it outside. A difficult task since the space for the name is very small

I've had it for a little while and so far it's amazing, it has very good range and so far I haven't noticed any delay. We'll see how long the batteries last, also I have it outside but it's not 100% exposed, it has a cover on top.

It has a seamless signal at a distance of 15 meters between transmitter and receiver with walls intervening, and it is confirmed to be truly waterproof. It is an economical and simple solution.

I put it six months ago in the village with the distance to the receiver being about 30 meters. It works great, has no problem with rainwater, and its sound is loud enough to be heard over music, radio, or television. Even from the vacuum cleaner (if you are in the same room). Very good purchase.

In a large chain, it said 220v, I didn't pay attention to the specifications, it is battery-operated which I don't like at all

Very good, helpful, without any problems, with powerful sound and good wireless communication between transmitter and receiver. Highly recommended.

Of course, it does NOT have a camera. It doesn't have any settings either. You just put in batteries and that's it. I liked that it had a window to write the tenant's name.
So far, it works fine and it hasn't gotten wet from the rain. The receiver works with batteries. I didn't realize that when I bought it. I would prefer if it could be plugged in. I will come back in a few months.

14/6/23 2 and a half years later, the doorbell works perfectly!!! We will buy another one.
