    • Easy To Install
Color: White 1 Receiver + 2 Buttons
This product is well designed & is easy to install. I chose the 2 doorbell model, & it was simple to select which chime I wanted for each door. There is large selection of tones, some louder than others, so you will find several that you like. I like that it was well made but inexpensive, it has held up well through lots of weather, & the buttons are large & easy to find in any lighting. The power unit is also compact. I am really happy with my purchase. ... show more

    • They work great, but I wish I would have gotten the battery operated kind
Color: White 1 Receiver + 2 Buttons

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. ... show more

    • I love this doorbell!
Color: White 1 Receiver + 2 Buttons
Very easy to setup. The base that plugs into receptacle is small and low profile. The tape works well with the push button. Screws come with it if you prefer to use them

    • Clever tunes and works great
Color: White 1 Receiver + 2 Buttons
This set works perfectly for the front and back door of the garage. We did different tunes (so many to choose from, we had a hard time deciding), so we know which door to go to, and people love it. It's easy to change the tunes and just plugs into the wall. They are wireless and we just set it to our internet. I'm in a raised ranch and plugged it in next to the front door. We were concerned if it would work at the back door since Ring Central won't work with the distance, but there are no issues with this. It's durable, and the size was a perfect fit when replacing the original doorbells. ... show more

This is exactly what I needed. Doesn’t require any sort of “smart home” to operate, is loud and clear, comes with two remotes that work from a good distance away, and is compact enough to share the outlet with my microwave tucked in the kitchen cabinet. I went through all 52 of the ringtones that come with it and settled on the first two simple “dingdong” style ones. The rest are kind of fun but would probably be annoying after the novelty wore off. My only concern is whether the supplied adhesive pads will stay attached to the vinyl siding around the door frame. I may have to apply some stronger glue. Time will tell! ... show more
