All Purpose Door Bell

This bell is LOUD, just what I needed for my profound hearing loss. It also has a higher pitch jingle to it. Could not expect more.

Low voltage Bell, was exactly what I wanted... For my particular use, I just wanted to use a simple noise, to send, strays away, from my lawn, rather than going to the door, to shout at them. I'd prefer not to have my yard, become an outhouse for the neighborhood strays, or someone's pooch, which the figure out (incorrectly) is entitled to use anyone's property's as a their pet's toilet. Easily wired project. And price point was just right for the simple little noise maker. I'll likely put a infrared sensor, to set it off, without any necessity to observe anything. I'm not without kindness for the neighborhood animals ... However I didn't intend for my property, to be noted, as that place you have to hold your nose shut 🤭, just to walk by.

Edit after a few months use: This thing seems to need constant calibration. The metal workings are just flimsy enough that with any change in the weather you have to bend and recalibrate it. NOT useful if you depend ona bell that needs to work. I have removed this bell from operation as it is worthless having to calibrate all the time.I had to add some solder to the screwless contact on the bell to give it better conduction. See my picture for reference. Once the solder is in place and you bend the hammer just right/into place then it's perfect. Some people complain about arcing but that is pretty normal operation for how this bell works. I put some dielectric grease on the arc point and it didn't seem to change anything except make a good spot for dust to collect so I wiped it ofd again.

not a nice sound but loud and that what was needed

Easy to install sound is loud

It rings starting at around 3.5v if I recall, and my power supply only measures about .1A at 5v. Maybe it's not seeing the full current, or maybe that's actually what it's drawing. I didn't test it for the 5v pin interference issues for e.g. Arduino/ESP32/Raspberry Pi yet, but if you're going to use it on that application, take a look at the other reviews - one reviewer used a diode on one side of the power feed to prevent causing fluctuations on the microcontroller's power input, and it would be good to review their solution.

I am hearing impaired, the bell is not loud enough.

Purchased for 95 year old who couldn’t hear electronic door bell. Easy to install and bell sound much easier to hear. Price was very reasonable. Quality was excellent. Good buy.
