Easiest thing ever to install and man it is loud. I bought 2 of them . I put 1 motion in my shop that is 60 feet roughly from my house and I plugged the sound chime up in the upstairs bonus room. It can be heard all over the house. I had a little trouble with the one I put near my back door because I can’t find the he best place for it to work but everything is great and best money spent .

Great little doorbell that does what we want. My store needed a new motion-activated bell after the last one kept startling guests. I picked this one on the theory that it between the volume control and huge number of chimes I'd be able to find ONE that would work. And I did! We're only on our third day with this chime but so far it's just what we needed. PROS: - The basic chime on this is really pleasant and hits that sweet spot where I can hear it but it doesn't startle guests. - The volume control has good range - the low is low and the high is high. I have a small store so we keep it on low but I like that I can adjust it up if I'm in the back. - It's nice to have the chime and sensor separate so it's closer to me rather than the guests walking in. CONS: - The range on the sensor is pretty wide which was problematic for my usage - it kept catching people walking by or browsing in the store. I cut a slit in a piece of paper and taped it around the sensor and also tucked it into a little nook next to the door and that fixed the problem. Obviously for those using this as a doorbell the wide range might be a benefit. For my purposes it needed some modifications. - The sensor unit requires either a mini-usb cord or 3 AAA batteries, neither of which it came with. Not a huge negative but something to be aware of if you want to use it as soon as it arrives. LIST OF TUNES: For those who, like me, want to know exactly what they're getting. I'm not terribly musical so I'm sure some of the tunes I've listed as "cheerful music" are super-popular and recognizable. Sorry. I didn't recognize them. Also all the music is very MIDI and nostalgic for those of us who grew up on early 90s video games. Full symphonies they are not. But the whole thing's less than $20; what did you expect? Also I only went through the whole round once so these are my first impressions. 1. Basic "Bing-bong, Bing-bong" My favorite. 2. Chiming "Bing-bong." Sounds like a grandfather clock. 3. Fur Elise 4. Big Ben's chime 5. Doorbell chime followed by, "How are you, please. Open the door." in a female voice 6. Polka Music 7. Cheerful music with a bird chirping in time. Very child-toy like. 8. Doorbell "bing-bong" three times 9. Cheerful little folk tune 10. "Santa Clause is coming to town" 11. Video game music 12. Doorbell followed by greeting in Japanese? I think? I'm fairly sure I heard "Arigato" 13. Classical Music 14. Chiming doorbell followed by something very much not English. 15. "Jingle Bells" 16. Cheerful tune 17. Bird chirp in rhythm. SUPER annoying. 18. Beethoven's 5th? 19. Doorbell followed by "Hello" in a male voice 20. "Ode to Joy" 21. Cheerful tune 22. Cheerful tune (long) 23. "Happy Birthday" 24. Classical tune (can't quite name) 25. (Customer interrupted at this point so missed it. Something musical) 26. Nutcracker Suite 27. "Happy Birthday" with a bit more of a flourish than the previous rendition 28. "Oh My Darling Clementine" 29. Familiar music 30. "Twinkle, Twinkle Little Star" 31. Cheerful, short tune 32. Music. 33. "London Bridge" 34. "Memories" 35. Familiar tune 36. Music 37. Waltz tune 38. Russian dance music

Fast shipment! I brought this for security purpose and it works great. Always good to know when someone come into my property. Would recommend!

LOVE this wireless door chime. We use it in a small business. We have the sensor near the front door, and the receiver is in our back break room. This allows us to know instantly when someone enters the business! The sensor has an amazingly wide range, so there's no way someone can walk in and not trip the sensor. The range between the units is sensor and receiver is good too. There is probably 100 feet between our sensor and receiver unit; plus several walls and doors that the signal travels through. It works GREAT, with zero issues. We've never had to replace the batteries yet, and that's with daily use for 12 hours per day. LOVE LOVE LOVE this thing. It has been a lifesaver for our business. So glad we bought this and would recommend to anyone who is needing a wireless sensor with good range!!

Spouse with dementia, leaving a room with her sitting she cannot remember to use the walker if she gets up, and very unstable.....placing this unit outside of her location sitting.....if she get up and inters the movement zone.....alarm goes and I go. Placing alarm in 110v area that you are in a plus instead of alarm on actuating unit, where you many not hear it.

This thing is Awesome! Very easy to set up,I use it in my lower level of my house. I put the sensor by the door going up and I plug the alarm up stairs by bedroom that way if any intruders I will know instantly. The motion sensor works great. I highly recommend 5 STARS

This is working fine for us, though we have had it only for a week. We use it to detect when the garage door opens, (by itself inaudible in the house), so when either of us comes home the other can appear to help guide the car into fairly cramped quarters, and assist in unloading any shopping.

I purchased this motion sensor alarm over 3 months ago and installed the motion detector inside my plastic mailbox which is about 75 feet from my house. I plugged the alarm receiver into a receptacle in my dining room. Whenever the mailman opens the door to the mailbox and places mail inside (which takes him only about 3 or 4 seconds), I hear a pleasant sounding Ding Dong, Ding Dong inside the house. I can hear it from several rooms away. Don't have to be in the same room. It was easy to install and setup was extremely simple. In the 3+ months that I've had it, I've had only one false alarm from a stray signal. It has never failed to work when the mailbox door is opened. I no longer have to keep watching out the window to try to see if/when the mailman gets there. I just go about my business inside the house and hear the alarm tones when the mailbox door is opened. There is a switch on the transmitter to turn it off if I should want to do that, but so far I've had no reason to want to do that. Still using the original batteries.

Works great. I used it for my puppy who wouldn't let me know that she needed to go outside to potty. She would walk down the hall to the door and just go if I didn't get there fast enough. I placed it in a room and it picked her up quickly, I even had to put (blinders) on it to make the chime sensor smaller. It is loud though.
