SURFOU Wireless Doorbell with 3 receivers 1 Button,IP55 Waterproof Doorbell,1300 FT/400M Remote Doorbell,55 Chimes 5 Volume,Colorful LED Flashing,110 db Loud Volume,For Home/Classroom

This is an awesome doorbell system. The sound is loud and clear, fun for the children at the daycare, and I can hear it not matter what floor I'm on in the building. The 3-pack bell system is perfect for three floors building. Loved the system so much I made my mom get a set for her 24 room house. Now she never misses a visitor.

I bought this for my elderly mother who has severe hearing loss. There are tones and ranges she cannot hear but with all the tones provided, we found one that she could hear. The additional transponders make it easy for her to hear the door bell no matter where in the house she is.

Just as described. Easy to install and set up. The ring options are hilarious, but more than sufficient. Overall a great inexpensive option

The doorbell set works as advertised and the positive comments indicate. But, two things surprised and annoyed me, and they may annoy the reader/potential customer as well. It could be that these issues are universal with all brands of these units? #1. I wanted to mount the doorbell with the 2 free floating screws included in the package, but there were no holes in the backplate to accommodate this, though the locations were clearly indicated. Really?? So, I had to take out my electrical drill and hope the bit didn't skip and damage the circuitboard. Not an issue for those who plan to use the double stick affixing option. #2 was somewhat Maddening. Now, this is a matter of taste to some degree, but In order to locate even two desirable chiming options amongst the 55 the electronic ditties snatched from public domain, all too many being kitchy classical abbreviated interludes, I had to listen to a few seconds of way way way too many offerings which quickly became a tortuous affair. Manufacturer Please Note: "Sometimes Less is More"! Try being selective as well and organized. Place the traditional choices up front followed by a few select other ditties in thematic groupings: Oldies but Goodies, Folk Songs, Holiday Charmers, Classical renditions from centuries long ago, Organ Grinder Rejects..whatever..... Do yourself and your future customers a favor or two and consider making these changes. Thank you.

Installed for an elderly person, this rings loud and clear, perfect for this application.

Easy to set up. My dad is hard of hearing so we put the receiver in the outlet by his chair. Now he always hears when someone is at the door.

Great coverage. Instant chime unlike my Ring doorbell that took several seconds to respond.

Great product
