Fosmon WaveLink 51018HOM Wireless Door Open Chime Transmitter (Magnetic Door Sensor | Battery Operated | LED Indicator) - 1 Transmitter Only (Receiver NOT Included)

Stuck to the door easily, we had a few milimeters gap due to the shaping of the old wooden door frame but it still works fine and simple easy instructions to pair with our existing bell system means reception are now alerted when someone comes through the door when they need to man reception. Thank you

Very good. I am particularly impressed by the range. 50m between transmitting switch and receiver, through a block wall and 2 stone walls. So impressed that I bought a number of extra units. I also like that multiple senders can be paired with multiple receivers, with different alert sounds. I have multiple outbuildings covered, each playing a different alert sound on 2 receivers in the house, 1 upstairs, 1 downstairs.

Purchased this as well as additional receiver for work as an alert for staff when someone comes in. Very easy to install with double sided holding strips. Lots of choice of tones and volume seems good but also can be changed.

Bought these for my grandmother so she can here when people come in her house. At first they worked great. But then after a month they started having issues, the main unit stopped receiving the signal and they generally became useless. I ended up returning them for a full refund.

Quick replacement, battery fitted already, simple to connect to doorbell

Within a very short time on our front door the units became unattached and fell off! We are looking into an alternative.

Brilliant use for my dad who has the odd wander due to Alzheimer’s, it’s doing a great job , would highly recommend

Not working unless i shake the sensors. not clear instructions. Not sure i the magnets have to stay next to the sensors? Bell not working either.

We purchased the old sensors and placed them throughout every single entry to our condo : doors, gate, garage door. We love it. Our gate sensor stopped working (after 3 yrs ) due to exposure to occasional rain and the battery connection got rusted. We bought the new version of magnetic sensor.I wish they sell Black color because as you can see, my gate is black. Of course I can paint it in black but they used to carry black ones.The downside is, it doesn't take the aa or AAA battery.Upside is... they provide the battery to you along with the sensor. And Smaller. It works great and still compatible with the old receiver.

Very simply to set up and works as expected

Works great.

We bought these sensors for a relative with dementia who has been wandering out of the house recently. Installation was very easy. Remove the wax paper to reveal the sticky tape, and put the large part of the sensor on the doorjamb. Repeat the same procedure with the small part of the sensor on the door. One of our doors has a thick frame and it was hard to line the two sensor pieces up perfectly but as long as they make the slightest contact, the unit will work.

workin good
