Fosmon WaveLink Wireless Door Chime with 500 Feet Range, 58 Tunes, 5 Volume Levels & LED Indicators for Home/Business/Office (1 Receiver + 1 Sensor)

Nice little door chime. Easy to install.Few chimes to choose.

I purchased this last year because my toddler sleeps on the 2nd floor and we sleep on the 3rd floor and I needed peace of mind knowing I had an extra set "eyes and ears" on her while we are asleep. If I didn't hear her awake and moving around on the baby monitor, I wanted to know that this would for sure wake me if she decided to venture out of her room while I was asleep (heaven knows that sometimes even a light sleeper can fall into a deep sleep!). It works like a charm!!Installation was quick and easy! We installed it at the top of her door (so she would never be able to pull it off) with the double stick tape that was provided and it didn't quite work because the door frame is a little chunkier- but it was an easy fix . I had extra double stick tape left over from something else so I just doubled up on the tape and that lifted it enough to get it to meet./touch the sensor.We plugged in the sound receiver in our bedroom and chose one of the many chimes/songs and adjusted the volume (the loudest level is very loud!) and synced them without issue. You will need a 2nd person to help sync them if you are more than 5 seconds away from the door. I should also note that there is a blue light that blinks with the sound/song/beat which I think is a great feature for the hearing impaired.I am writing this review a little over a year after purchasing it because our receiver stopped working, but I emailed the company and they sent me a new one for free! There is a lifetime warranty on their product- how amazing is that?! The process was quick and easy, just a few emails explaining the problem, verifying my purchase on amazon (send them invoice from your "previous orders" and verifying address.) WOW- not many companies stand by their product like this and I was already pleased with our door chime, but this experience just took it to another level!Totally recommend this product for your adventurous toddler, secret mom power to 'mysteriously' appear when a kid opens a door, or business!

We got this because we have a young adult child with brain injury who escapes out the back door when no one is looking, and also likes to go into the bathroom in the middle of the night and overflow the sink. After waking up to an inch of water on the bathroom floor, we decided we needed to take drastic action.Because our other daughter has autism, we couldn't use the alarms that beep or sound like a siren. We needed something more pleasant that would still get our attention in a sometimes noisy home. When I found this alarm that plays music, I thought it might work for us.This alarm arrived quickly, was simple to install, and works well for our family. We found two different songs to signal the back door and the bathroom door. There are enough different kinds of sounds that you are sure to find something palatable for your household. There are several different door bell chimes, a siren or barking dog (if you want to scare off burglars), and so many tunes we never made it through all of them. We just picked a couple that were acceptable to us.The receiver has 3 volume settings. We use the loudest one, and it is audible at least 3 rooms away, through plaster walls and doors. So, while it wasn't our primary reason for buying this alarm, we now have an additional security feature on our house.We live in an old house with plaster walls. The bathroom door is about 30 feet from the receiver, with several walls and heavy wooden doors in between. There is no problem with the signal being sent through these obstacles, even when all of the doors in between are closed.I recommend this alarm to any caregiver who needs something to let them know their loved one needs some supervision. It will change your life!

And it chimes when on loud setting loud enough to be heard 2 hollow-core doors away from the chime. So it's fine. But only as a chime. Not an alarm. Update 2023-06-30: 1) We have paired 2 sensors and, with a little fiddling, each elicits a different sound from the base unit. The font door elicits a Bing-Bong. The slider to the patio a Wah-Wah claxon. OK. Good. 2) We put the base station near the bedrooms on a timer. It gets power from Midnight to 6 AM only. Otherwise is unpowered hence silent. Settings are remembered. OK. Good. 3) But the sounds when triggered by the sensors only play once and then shut off. So if you don't wake up at the first instance of the sound from the base and as the claxon will shut off all by itself(!) then the perp can just walk right in. Bad. Very bad. It would be better that the claxon continued to sound until someone awakened, got up, called the cops, went to the base and, when safe, turned it off. Or the claxon could time out after 1 hour - in case we were away on vacation. Adding more units won't help because the sounds - bing-bong or wah-wah - stop on their own within a few seconds. Just reporting this. Door chime: good. Alarm: very bad. Please be aware.

I bought this in August 2023 and the battery in the receiver just died. It works great… only issue I have is the description says the receiver takes a AA battery… it does NOT… it takes a 23A 12 volt alkaline battery… not a big deal… they are cheap…Anyways… cheap investment… works great…
