⭐️⭐️⭐️⭐️⭐️ Reliable and Easy to Use – Great Range and Features!
I purchased the SANJIE Wireless Door Open Alarm Sensor Chime for my conservatory to let me know when a door is opened, and it works perfectly. The setup was quick and straightforward – no complicated wiring, just pair the sensor and chime, and you’re ready to go. The 800FT operating range is impressive; it easily covers large spaces without losing signal. The 55 chime options are a nice touch, allowing you to choose a tone that suits your environment. The volume control is handy too, so you can adjust it for quieter or busier settings. The sensor is very responsive – it triggers instantly when the door opens, which is great for security and customer alerts. Overall, it’s a reliable, affordable solution for monitoring doors. Highly recommended for shops, offices, or even home use!

Think ahead where you want to install before buying.
I bought two of these. Easy to fit and programme. The chime is loud and clear. It is very handy that you can switch the mechanism on and off on the sensor fitted onto the door. Only four stars because the door sensor is unreliable; it seems that they have to be fitted so that the two pieces almost touch, and that is not possible with all doors.

Great
This door bell is amazing. We use it so I can hear my 5 year old son get up in the night before he ends up at the end box my bed 😆. It works really well

Stopped working - returned
Great at first but stopped working after 3 months with the plug chime going off for no reason even with the sensor switched off. Also states it takes CR2032 batteries but the model we received takes CR2450 which we now have an abundance of after returning the faulty item.

Brilliant for keeping people/kids safe
Bought for my in laws house as my FiL has mixed dementia and is prone to leaving the house. This now let's my MiL know when he opens the door. There are a number of options for the music/ringtone it plays when the door opens. It also has a volume control and was easy to install with the adhesive pads supplied. Would also be great for using with kids.

Used on my doors and windows after an attempted break in. Super loud, there is no volume control so you can turn it down and I swear it would wake up the dead.
