The ease of installation and functionality.
One of my senior family members needed a door bell. Many senior people don't realize that a new door bell is very easy to install. There are no wires to run, just plug into a standard AC outlet, then use the double sided sticky tape allowing the user to press the bell button on the outside. I think it took me five minutes total. The new bell system has two receivers and allowing one for downstairs and upstairs. My family member was extremely surprise how easy it was and was and how well the product functioned. Also the design won't block the whole outlet. Great product!

Simple, Great Price, Easy to Install
Was in need of a simple doorbell for front and back doors and this works great. I like that I can change the sounds of the bell and the volume. We also liked that although there were screws, we opted to use the velcro it came with which made it so simple to install. So for a simple bell solution for the price this is great.

Easy setup, great range; affixing with screws requires drilling tap holes into the doorbell itself
Recommend: Yes Would I buy again? Update 7 months later after several rainstorms .... Yes based solely on aesthetics, setup, and functionality. After seven months and several rainstorms, a few going days at a time, the outside bell is still going strong. I will update on longevity over the next year. Will update the missing star if it makes it through two seasons ... How it works: The doorbell is a wireless transmitter that runs off a CR2032 battery. (I forgot to mention this in my first posting but I switched out the battery that came with the unit with a fresh Duracell - this ensures longer performance.) The doorbell can be affixed with the supplied adhesive and/or the two supplied wood screws. The receiver must be plugged into an AC outlet. The manufacturer says up to 1,000 feet line of sight. I found +/- 300 feet with obstructions is more like it. When the doorbell is pressed, the button lights up blue for a few seconds and then goes dark. The doorbell is not backlit, which I imagine is to conserve battery life. The receiver has a variety of ring tones and volumes to choose from. The transmitter has a gasket that produces a snug seal. The unit has an IP55 rating. So what is an IP55 rating? The first number is the dust protection rating and the second number is the water entry rating. The highest dust rating is 6 and the highest for water is 8. A “5” dust rating means the doorbell transmitter allows a limited amount of dust and any incoming dust should have limited effects on its functionality. A “5” water rating means it should protect against sprinklers and intermittent rain. This unit is not rated for complete submersion in water, and is not rated for frequent jets of water or prolonged contact with water. Kudos. Setup could not have been easier. The transmitters and receiver were paired up at the factory. Adjusting the volume and type of chime on the receiver is simple and intuitive. The box includes two doorbell transmitters. You can use both at once or use a single one keeping the other as a replacement when the first takes a dump (which I imagine will be after our next major multi-day rain storm). I am pleasantly surprised (shocked actually) as to the range of the transmitter. My units are about 300’ apart with two walls in between. After seven months and several rainstorms, a few going days at a time, the outside bell unit is still going strong. Pleasantly surprised. Quibbles. If you wish to affix the doorbell transmitter using the wood screws or to change its battery, you will have to remove the transmitter’s back. The back is held to the case with two tension clips. There’s a recessed area to place a flat head screwdriver; the back pops off with a gentle twist of the screwdriver. When I opened the back, I noticed part of the clip securing the back and front got damaged. Fortunately I was able to get the unit back together and seal properly, but this suggests the next opening (e.g., battery change) may shear the clip entirely. That sucks. Next, you will need to drill holes into the back of the unit for where the screws will go through. Making your own tap holes for screws can be tricky for the non-handy types – make the holes too big on the doorbell case and it’s a portal of water entry! If you don’t own a drill, you might be able to screw directly through the plastic casing though it’s pretty brittle so you might risk cracking the back. Using a drill may be a deal killer for the non-handy types. And finally, the doorbell is not backlit which is good for battery life but a challenge for nighttime visitors to find the (black) doorbell. Suggestions. I recommend applying a thin film of silicone grease (e.g., DANCO Waterproof Food Grade Silicone Grease for O-Rings) around the gasket. This will enhance its IP55 rating. Next, if you use screws, add a thin layer of silicone calking (e.g., Gorilla 100 Percent Silicone Sealant Caulk, 2.8 ounce Squeeze Tube, Clear) on each screw and over the heads to prevent water from entering through where the screws meet wood or concrete. Bottom line: I’m pleased with the aesthetics, setup and functionality, especially given this unit's relatively low price point. Update: After seven months and several rainstorms, a few going days at a time, the outside bell is still going strong. No conflict of interest. I purchased this product for its intended use. My review reflects my personal experience with this product. I have no affiliation with the seller or the manufacturer. I have not received any compensation whatsoever (cash, discount, rebate, merchandise, etc.) for this review.

Perfect For My House
I loved how simple this process was to install it. I used the self stick piece to adhere it to my enclosed patio door. Even though my patio and door are all metal this works flawlessly. I was hesitant because of the description not to use this on metal because it might interfere with the doorbell function or the loudness of the chime. No problems! I bought this just weeks before Christmas and had a Christmas melody on that was perfect! It’s still on that song so I have to change the melody to something else. It comes with loads of melodies it can play so I just have to pick one. Changing the melody is simple as 1, 2…done! Love this doorbell!

Ding dong! You’ve hit the jackpot.
I love them, easy to install. Great range even thru concrete walls. The receiver is about 200ft from the fence with 2 layers of concrete walls between and it works flawlessly. Easy to operate and a million sounds to find your liking. Gets plenty loud if you need it to, I have it in the middle.
