SadotechWireless Doorbell for Home - 1 Push-Button Ringer & 1 Chime Receiver, Battery Operated, 1000 Feet, Cordless Waterproof Door Bells w/LED Flash, Classic White

Very good range for this wireless doorbell and a good sound.

pleased

Very nice

Good sound and range not battery

Does as a door bell should however push button a bit flimsy

Stopped working after 1 year …. Not recommended

we bought 3 units for multiple doors and all worked well for 3 years, but with little use of each one. then one of the doorbells stopped working so I changed the battery and the light came back on when pressed. however no sound from the receiver unit. I tried twice to reset using the instructions, but no chime from the speaker unit. it appears the transmitter element has stopped working and it is not possible to buy a spare bell push alone but have to buy a full kit. What a waste. I am concerned now that the other units will stop working, so do I spend a lot buying another one, or try another system and buy 3 complete new kits

Less than a month old ,installed for only 25 days, totally not waterproof very disappointed. My advice do not buy.

Got this to replace my previous one which was very similar and lasted 7 years. (not the same brand) Seems good so far, very easy to install and worked immediately, no issue pairing. Nice to have a choice of tones, I chose one that does NOT sound like every doorbell in every commercial on tv lol.

Considering this was very inexpensive, it works quite well. It's plugged in the downstairs hallway and the volume is loud enough that it can be easily heard upstairs. I really like the fact that you can set different sounds. I used the adhesive that came with the package and did not screw it into the outside door frame. So far it's sticking very well.

Update 11/7/21I contacted customer service via email to find out if it was possible to resync the doorbell and chime. Turns out there is a way! Doorbell is working just as good as day one.Customer service response to symc the button and chime:1. Reset the Plug in Receiver (Do this if you need to change ringtones, if your receiver is randomly chiming or if step #2 did not work)a) Please clear out all settings of your plug in receiver by pressing the Music Control button for 5 seconds or until you hear a "pairing alert chirp" and see a quick flash.b) Verify that your push button is not connected to the receiver by pressing the push button, the receiver should not chime.Once it is done, do the pairing operation:2. Pairing and Assigning/Changing Ringtonesa) Select desired ringtone by pressing Music Control button.b) Set Receiver into pairing mode by pressing the Volume and Music Control buttons on the receiver simultaneously. A chime and LED flashing will indicate the ready status.c) Quickly pair push button with the receiver by pressing the push button.d) Press again the push button to hear the tune you selected, which means that your operation is completed successfully.Original Post:I purchased this item back in Nov 2018. Initial setup was easy, i used the double stick tape. plug in the chime part, peel the tape, stick it to the button, press the button to the door. In my case the chime plugin part is right on the other side of the door, talking 3 ft away. That was pretty easy. For the first year or so it worked great. Then it started to not chime when the button was pressed. Sometimes it worked other times it wouldn't. Took repeated presses and it would chime. I replaced the battery and it worked a little bit better. Still would not always chime, but a quick double tap seemed to always work. Figured if someone needed me that badly they would press the button twice anyway.Fast forward a few months later, pressing the button would light up the button but no chime at all. No matter how much you press the button. The chime plugin receiver works fine, turning up the volume, changing the right tone all work. Pressing the button does nothing.For the price it's not a bad doorbell, but very unreliable. Might last a year, might last a month. There seems to be no way to resync the doorbell to the receiver so you are just out of luck when it stops working. I would not recommend this product to be reliable enough to alert you grandma is okay or for anything that requires any kind of level of reliability.

The one I recently purchased replaced the same product that I had for several years that stopped working. It's super easy to install and I like the ring tones. Very affordable.
