Easy to install and setup. I like the model with the plug in receiver/ringer. No batteries to change except for in the doorbell sending units. I will need to revise this review if the button batteries don't last though. Haven't had much luck with batteries lasting long during the winter with past wireless doorbells. So far the range on this model seems OK and the ringer is loud enough to hear anywhere in my apartment. The ringer is mounted in the kitchen and I can hear it from the living room and any other room in my apartment. Bough the model with 2 doorbell buttons. Nice that the buttons can be setup for different ring tones for each button. I setup the back door button with a different tone than the front door.

Very very good easy to setup and change tones. Can set the two for different sounds one for front door one for rear door. I like it reasonably priced

Easy to install, works great. The old one that I had did not have the picture of a bell on the button, so people didn't always realize I had a doorbell. They see this one, so they actually ring it instead of knocking. I recommend it.

These doorbells work well and are really easy to set up (the hardest part is picking which chime to use). There are a ton of options, each doorbell can be set to a different chime, and the volume gets loud enough to hear from several rooms away if you need it to. I ordered this specific set because I have a large house with a front and back door that are both commonly used. The biggest benefit to these is the ability to set them each to a different sound. Now, when I hear the chimes, I know exactly which door to run to. My house didn't come wired for bells so I knew wireless was the easiest option and these were some of the least visually obnoxious that I could find. Many of the doorbells that I saw while shopping appear designed for alien spaceships with lights and weird shapes. These are just noticeable enough that people realize you have a doorbell. I really wish that AVANTEK would offer a set of two remotes with a battery operated receiver. I was torn, when ordering, between this set or just getting two battery operated single remote and receiver sets. I went with this one as it was the more economical option, but I’ve regretted it. The issue that I have run into with this set is that having it plugged in all the time means that it gets in the way. I wish I had the option to put the receiver somewhere truly out of the way. Additionally, the chimes aren’t always remembered. When the receiver was unplugged to move it from one outlet to another after initial programming, it forgot the chimes that were programmed for both doorbells. Although, later, the receiver was bumped and knocked out of the outlet and when plugged back in, it still remembered the chimes. A final time, the power went out for over an hour and when it came back on, the chimes were still remembered. So it seems to be fairly hit or miss. Another consideration is that when the power goes out, your doorbell won’t work. While this is true of wired doorbells too, the battery powered options don’t have this concern. If you live in an area where you have common power outages you probably want to consider looking elsewhere if you plan on having visitors during storms. One final note, is that after having these up for over a month, one of the remotes has begun to yellow slightly. This particular remote gets full sun for about half of the day and has been rained on an awful lot. I’m not too upset about it considering the conditions that it sits in, but it’s something to keep in mind. The other remote, which is placed on a door that’s covered by a roof, hasn’t yellowed at all. Overall, I would recommend this wireless doorbell set as a great, affordable option that doesn’t draw too much attention to itself. If you’re not on a strict budget or if you live in a home with limited outlets, I would recommend spending a little more for the battery powered option.

Incredible sound in terms of quality and decibel. The highest volume can probably be heard from the moon, so if you're hard of hearing or work in a barn a mile away, you'll STILL hear this doorbell on the highest setting. I'm being hyperbolic but only 90%. So many songs and alerts to choose from, it's daunting but fun. Every time I thought I had chosen one I'd click a few more just to hear a few more options then I'd have a new favorite. Some of the sounds are hilariously distinct and something I'd never actually want to use as a doorbell but I'm also half inspired to use the ridiculous ones simply for that reason. Easy to put into place, easy to figure out, aesthetically pleasing, and did I mention it's loud enough to be heard during a demolition derby? It probably is. I got two doorbells so I'm splitting my sounds up - one normal doorbell with a pretty song (I'll probably go with Fur Elise) at one of the lower volumes and then a secret doorbell near the real one but out of sight a bit for people I KNOW and LIKE to ring, that way I'll always know whether it's someone I want to see or someone I wasn't expecting. The friend-doorbell sends a rooster crow sound through the whole neighborhood when it goes off. I laugh everytime.

Now that we have made it passed the Halloween season, I can report this doorbell works well. The only question I have is the durability as both door locations face north and are exposed to harsh weather conditions.

Wow! I love it. Received it today and installed it right away. It's very easy to install, and setup. Instructions are clear and simple. I like the variety of sounds. Wish there was an easier way of selecting tone instead of having to skip and hear each one. Some of them are obnoxious in my opinion, I mean who wants a pig oinking?? But anyways, the reason I chose this over other wireless doorbells is pretty much because description stated that each doorbell could be set to a different tone. I'm using one for the front door and one for the back. I used the adhesive that comes with, to start. I don't know how long it'll hold but before drilling and making holes I want to make sure that it'll work fine and that the spot for it is right. Honestly I recommend. My house isn't too big, but sometimes while watching tv we can't hear people knocking at the door so this will be a little extra help. Like I said, setup and installation was super quick and easy. It offers 52 tones, some of them are nice melodies some are animals and wacky sounds. I like that I can distinguish which door people are calling from . Adjustable volume and tone can be switched very easy also. It was a good price, I just hope it lasts.
