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

Very good, sensitive, adjustable volume, and a variety of ringtones to choose from

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!

I wish Fosmon could teach other companies how to provide customer service. Theirs is amazing and so is this product. The directions were pretty easy to understand (so many products don't come with instructions), however I was not sure if I could pair up 2 sensors with the same 5 receivers. Weiung (in the tech department) assured me you could do just that and he stayed on the phone to make sure I was able to be successful. After I hung up I had another question, called back, and AMAZINGLY was immediately connected to Weiung. WOW is all I can say! Another nice touch, he encouraged me to call back with any question/concern. As for the product, this product has saved me already 4 times in the first 3 hours of installation. When my wandering husband opens the door the receivers go off and I can get to the door before he can go too far. THANKS Fosman!!!!

It's great when it works. But the chime has days where it works all day and other days were it doesn't work at all. More days of not working than working. This is my second chime from this brand - first one was great, worked all the time. This one, the items that are attached to the door are much smaller which makes me wonder if they're less powerful than the older model.

covers most of my rangehappy with it

Easy to install. Has good range.

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!
