Door Chime, METAK Wireless Door Open Contact Sensor Alarm with 500 FT Range, 58 Chimes and 5 Volume Levels for Business/Store/Home/Office When Entering, 3 Transmitter + 2 Plug-in Receiver

We have been using this brand of doorbell at our businesses for about 5 years. We love it. You must align the two pieces properly in order for the chime to go off. This isn't difficult to do and assures that it works well. We have never had a quality issue and you can adjust the loudness. This works my planning on the front door and then a Sunday is sent to the bell in the back of the office where someone is working so they can hear someone enter and leave. Keeps everyone alert to customers.

We purchased this door chime for our small business and it works great! I was skeptical at first due to some of the reviews, but I took the chance and I am happy I did! It was easy to install. I just plugged it in, set my chime, chose the sound level and it was ready to go. I have moved it in multiple different spots to see where it would work best for us, so if you need to move it around a bit, it is easy to do. The sound quality is great for what we needed. You can’t beat the price either. Well worth every penny spent, even if it happens not to last for years to come, though I have no doubt it will.

Exactly what I needed for my little office! I was always afraid to leave my desk too long or go to the bathroom because I couldn't hear if someone we're to come in! I'm in a storage facility so it's important for my protection also! Ilove all the different sounds and chimes it comes with. It was extremely easy to install, plus it came with its own batteries which was nice since I didn't have any at the time lol! Great product 👌 👏 , you won't be disappointed 👏

The media could not be loaded. 5 stars for price point and ease of use, 3 stars for instructions and hard(ish) to use mute feature. This unit is very simple and does indeed work to alert you when a door is opened. Unfortunately, the instructions are oversimplified and sorting out things like tone and volume are not intuitive. Below I listed what I learned in the process and hope it helps the next buyer. Setting it up took way longer than it needed to, and a lot of trial and error; but, the finished install works great and I would buy again.STARTING: When you get it, you just plug it in. The chime noise comes out of the unit at the plug, so consider where you want to hear the chime when choosing where to plug it in (and it has to be within 500 ft. of the door you're monitoring).TONE: There are only two buttons on the unit. (1) The tone button, which is marked with music note icon; and (2) the volume, which has a sound icon. Note which is which before you plug it in (they are hard to see, and if you’re plugging it in behind or under something like I was, even harder). To adjust the tone you quick press the tone button, once for each tone. What the instructions do not tell you is that to get to the next tone you have to press it again before the current tone ends, otherwise it just plays the same tone again and you may think it's not working. When you find a tone you like, you can just stop - there is nothing more you need to do to set to that tone. There are 58 tones to chose from, from simple chimes to melodies. If you want to go back to one you heard a few tones ago, can go in reverse order by holding the tone button down for a few seconds until you hear a beep.VOLUME: Similar to the tone, you short press – and need to do so before the tone ends. There are 5 levels. From mute, it goes up through the levels, then makes a two-beep sound, then goes back down. It's a bit of a hassle to run through them and get back to mute every time you want to adjust or mute. FYI - In my attached video the tone is very low and may be hard to hear. I have it set to a lower volume and was about 15 ft away from the plug in unit. It does go up loud enough to be really annoying if/when in a quiet space.BURGALAR ALERT: You *might* be able to use this as an intruder alarm. There are various tones and volumes, some are long and definitely loud enough to wake one up or hear through normal volume music/regular house noises *IF* the unit is plugged in near you. It does not, however, have a screaming loud alarm like, for example, window glass break sensors do. The maximum distance from transmitter to plug in unit is 500 ft., so you likely can't put the transmitter on one side of your home and the plug in unit (chime sounder) on the other side, unless your home is smaller. So if you live in a studio, it would absolutely work, but if you live in a 2-story home and would need to hear it sounding from downstairs, no way.MUTE: My one gripe about this unit is that's it's not easy to get to mute. Mine is plugged in behind a dresser and I have to reach back there, the press the button repeatedly until cycles to mute - and I'd likely go through that a few times because with the needed quick press it’s easy to miss stopping on mute. For my purpose I want to be able to turn it off and on daily. I would have paid for an upgrade for a remote that switched it off, or an app, or even just an on/off button or toggle on the unit. Unplugging it resets things, so that's not a good option. As a hack, I used command strips to put it up and I just pull off the small magnet to disengage.PAIRING: It comes paired, you just pull off the battery tab and it works. There are instructions for pairing, (to be used if you have multiple devices or I guess if it un-pairs for some reason), but on mine it wasn’t necessary. Just FYI - this is not a smart device, it pairs only from the unit to the transmitter, not to your phone. For the money that's fine, but with all the tones and features advertised one mistakenly might think it does.INSTALLING THE TRANSMITTER: I could not install as pictured because of my door trim. Easy enough to fix, I just put the large part of the transmitter on the door and the small magnet part on the edge of the trim (see picture). I also used velcro strips instead of the included adhesive, for easy removal of either side of the unit. FYI - the transmitter has to be very close to the magnet to work (1 cm), and you need to ensure the transmitter and magnet are facing each other the right way (there are marks on it to indicate, and you can play with it before you install - the instructions do cover this part).

Super awesome, I'm very happy with the product and I'll definitely recommend it to anyone who's is looking for a door chime.

We use this door chime for our restaurant. You can't hear when somebody comes in if you're in the back washing dishes, so this was the perfect solution. They love the volume control and multiple chimes.

I got the 5-transmitter/2 receiver kit. It only came with 10 screws, even though you need 20 to screw-mount all the senser pairs as shown in the instructions.Trying to get the sensors into the right alignment so they would work properly was a hassle as well. Each transmitter came with arrows on each half that I assumed should be lined up in order for the sensors to work properly, but after mounting, I found I had to remount the sensors with the arrows misaligned in order to get the sensor to work properly.

We love these ! Only thing is the stickers could have a stronger stick
