Wireless Door Open Sensor Alarm Chime (Operating Range 600ft, 58 Chimes Tunes) BITIWEND Wireless Anti-theft Window Sensor Alarm for Home Store Office with 1 Plug-in Receiver and 1 Sensor, Black

Looking after my elderly mother who suffers advanced dementia. To be alerted by the door alarm when she leaves her bedroom enables me to be in other parts of the house and know that she is still in her room; which has been made safe. Moving the plug receiver to my bedroom overnight gives me peace of mind that even when asleep I will know straight away if she leaves her room. A great buy for me.

I can't believe I'm writing a 5 star review about a doorbell, but honestly this product is remarkable. Worked out of the box, clear instructions. Two door pushes and three sounders, one downstairs, one upstairs and one in the summerhouse at the bottom of the garden. Two different tunes for each door and the tiny transmitter even works the summer house sounder fine. The tunes are so good as well, polyphonic with harmonies, and the blue light pulses with the music!! We actively look forward for callers and feel like Marge & Lisa in the "Senor Dingdong" Simpson episode. Best thing we have ever bought from Amazon. Highly recommended.

This review is on the set with 3 bell units.OK, first off is that you get 3 plug in 'bell units'' and 2 door buttons. Obviously you only need one door button, but I put both up, one either side of the door. because people have a habit of not seeing the button and just banging on my door. I am partially deaf, hence why I wanted more than one unit so I can put all over the house.The door button comes with VERY strong sticky pads, but also screws and wall plugs so you can drill holes into brickwork etc if you want a really good fixing, but against a UPVC door frame the pads arer perfect. Just clean the door frame first and then use a little white spirit to finally clean the little place you want to stick the pad to remove any grease, thus getting the best adhesion possible.The bell units just plug in. You have 5 volume settings and dozens of different chimes from simple ding-dongs to full tunes. The best bit is that you can set each bell unit independently so different volumes and chimes on each if you so wish. All the bell units will ring at the exact same time of course when the button is pressed,We put one in the lounge, one in the kitchen and the last on on the upper landing so you can really hear the door bell wherever you are in the house.Great value and so far an excellent purchase. Throroughly recommend these.

Seems to be a good product. Ultra simple to install even for a Wrinkly. Taking it beyond the basic step makes me nervous as the scant instructions are written in Chinglish with the minimum information, unlike some that contain so much that they are equally unintelligible.On the apparatus there is no information that indicates who this is manufactured or marketed by, which I find odd. The only information given is that it was made in China, which even an idiot could guess.A tip is to plug all three receivers into a power block set your preferred noise and 'pair' them with the transmitters (bell pushes) before installing the outfit. This way you will not find yourself darting all round the house. After this initial procedure just fix the door pushes by the doors and plug the receivers into power sockets where you want them.Warning - the chime tones are as naff as with similar products on the market, so be cautious about listening to over 50 of them!I hope this outfit will not be affected by other wireless devices, but the description at the point of sale is also scant and there is absolutely no information in the user's 'manual'.

Bought this for two reasons. Firstly I was fed up with nobody ringing existing doorbell which is to the right of the door, and secondly the first doorbell was beginning to play up downstairs but fine upstairs (2 units).The unit us smart, and extremely easy to install. No instructions are necessary. The adhesive tape stuck to the door frame fast. And being black it’s actually being used now. There are lots of tunes, in fact too many. But I did like the birthday ring. Just wish I’d purchased it the week before for when my daughter and family came round for dinner on her birthday.

We have a glass display cabinet in the restaurant that attracts the attention of anyone walking by. So I needed a deterrent. This is a useful tool. It was easily installing with the sticky double sided tape to attach the magnetic sensors.The bell or alarm it self needs to be plugged in to a plug socket. It pretty loud and has actually led to people not touching or opening the glass display cabinet.It’s feels like it is made from pretty decent stuff. I chose this colour as the cabinet has black frames. It matches well.

What can I say about this wireless doorbell.Well the unit itself looks sleek and smart it has four levels of volume and loads of different tones.We have the chime plugged in the next room in the kitchen on level 3 volume and is loud enough for us to hear in the next room. There is loads of tones from simple ding dong to songs like happy birthday, to some familiar Xmas ones and all sorts of others in between. The push button has a blue light that lights up when pushed so that callers know the bell is active and the plug in receiver also has a blue ring of light in the middle that dances to the tone selected. This is a nice little feature as if your hard of hearing or have a noisy home the blue light alerts you that someone is at the door.The unit is so simple to install, the receiver just plugs into a standard UK plug socket and the push button can be installed either with the two screws and wall plugs that are supplied or with self adhesive sticky pad that's also supplied.Overall for the price this is a great buy and you really can't complain. I would have no hesitation to recommend this to other people.Very happy with my purchase.
