Wireless Doorbell, SECRUI Door bell Over 1000ft Coverage with 2 Plug-In Receivers, 1 Waterproof Push button, 52 Chimes, 110dB loud Sound Colorful LED Flash

Easy, nice clear sound
I had battery operated doorbell before, but this looks better and works well. Installation consists of taking off paper and putting bell-push sticky part on the lintel. It holds! Thrilled to have a doorbell again.

Easy setup, great range; affixing with screws requires drilling tap holes into the doorbell itself
Recommend: YesWould 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.

Easy to set up
I didn’t work on any special stuff like different sounds or volume. I just plugged it in and it works. It’s loud enough, it sounds like a doorbell. The only mistake I made was buying a black one that I mounted on black door trim so I had to make a small sign with an arrow and text saying “doorbell”. Works great

Pretty Cool Little Devices
We got one with two buttons and two receivers. The receivers are great because you just plug them into any inconspicuous outlet. We have one upstairs and one downstairs so we can always hear the doorbell. The buttons are simple and just take a 2032 flat battery. I doubt the batteries will need to be changed often. There are a bunch of songs available. We found the two we liked best and configured it so each button triggered a different song. That way we know whether the front door or the gate button is being pressed. The connection distance is pretty decent — I had no issues. One tip – they come pre-programmed. It’s easy to change the song, but by default it will be the same for each receiver and button. If you want them to trigger separate tunes, you need to clear the programming first. It says this in the manual, but for some reason it took me awhile to try that. These are much better and cheaper than the old school door bells we bought at Home Depot.
