Sinvitron wireless doorbell with 1 Remote Button and 2 Plugin Receivers Operating at over 500-feet Range with 36 Chimes, No Batteries Required for Receivers

This has a great selection of musical chimes. I appreciate the fact that it is battery operated so that I do not have to get an electrician to install it. On the flip side, it uses an A23 battery like  Energizer A23 Battery, 12 Volt - 4 Batteries  (which they do include). This isn't expensive to replace, but you are unlikely to already keep those around the house. Also note that with my weak hands, I had to get help to remove the battery cover. My teenagers could do it. Anyway, installation was simple with a choice of strong double-stick tape or screws.

I'm happy with this product. It's very affordable and the quality of the plastic used on the housing is good. The mechanism hasn't failed yet after about 1 month's use which is surprising for something made in this price range from that certain country! If there's one little peeve, I think there's just too many chimes to choose from. Like some other reviews, the chime jingles are long, like songs; kind of irritating and time consuming in the beginning during setup. Other than that, great product that works!

Door bell works. One problem so far. My daughter who is petite rang it about three days after we put it in. It rang fine. about three hours After she left the door bell rang and would not stop. No One There! I checked the ringer part outside the door and it was stuck in the pushed position. I pushed the top part of the ringer and it released the button. Still works but I am keeping an eye on it!

I just receive this door bell and I am disappointed but it is my own fault I was wanting a push button for the front and back door but I received 2 plug in receivers and 1 push button for the front door, I only have a small house and don't need 2 receivers. I need to read more about the product before I but again.

Took a chance on this since I live in a mobile home with metal skin and not much gets though it for wireless. Was hoping due to the extreme range that this would work and boy does it! Easy to install and set up and I have the Star Spangled Banner ring that plays. Drives my 2 dogs wild! Great product.

Had purchased a wireless doorbell from a local big box lumber store with constant failure. Took a chance, based off independent reviews, and purchased the sinvitron wireless before the holidays. Had fun with the holiday chime and has not given me any problems. The 36 chime selection provides a vast array of options. Fun, fun, fun....Great device......

So far so good. Perfect size. Very easy to install. Took me about 5 minutes to install the transmitter. Liked that it comes with double sided tape and screws for installation. Sound quality is good on most tunes. Like that there is a variety of tunes to choose from plus a ding dong. Good item for the price.

Great product easy to use. Front door button is big enough that nobody misses it. The two different chime boxes worked excellent. One upstairs one downstairs both different sounds. Loud enough for one floor.
