Philips Wireless Doorbell Kit, Battery-Operated Reciever, LED Alert Lights, 1 Push Button, 32 Melodies, 3 Volume Levels, 150 Ft Range, White, DES3140W/27

Easy to install and loud! Can be heard from a long distance.

Easy to set up and works well. Loud enough to be heard on the 3rd floor of our 3-level house.

Very straightforward and easy to use device.

Loud enough to hear from an adjacent room. Good sound. Bright blue blinking alert lights, especially if you are hard of hearing. Good selection of musical tones, songs. I especially appreciate the fact you can take the receiver with you to another area, room, and not miss a single visitor. Works well. I like the optional adhesive pads, as I don’t like putting holes into my wood door frame. No plugging up wall outlets with this wireless capability. I seldom give 5 stars to anything, but even as made of plastic I give it a 5. Another convenient thing is you can stand it up, hang it up, lay it down, or reposition the speaker in direction of sound. This one’s a keeper in my book.

I'm renting the basement section of a house and bought this so my housemates didn't have to holler if they needed the laundry room, etc. the button is at the top of the staircase, but the bell is 3 rooms away, with several walls in between. The signal activated the bell each time, no problem. Super easy to set up, and there's plenty of times to choose from, and plenty of volume settings. Can't recommend it enough!
