Fosmon WaveLink Wireless Door Chime with 500 Feet Range, 58 Tunes, 5 Volume Levels & LED Indicators for Home/Business/Office (1 Receiver + 2 Sensors)

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

Easy to install. Has good range.

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

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.

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 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!!!!

Don't buy alone, needs to be a set. I bought it to replace one that broke, but not compatible with what I had.
