🔔 uxcell Industrial Continuous Sound Electronic Buzzer 80dB - DC 3-24V, 30mA Review

Audible alarm required when entering driveway. It was easy to expand our existing security system. Works well, can be heard throughout the house.

Use for Lights Reminder in 95 Civic. Easy installation and works perfectly. I wrapped everything in duct tape because it was too loud.

I use this buzzer in combination with a night shield and a pressure sensor that warns me when I start grinding my teeth at night. With a 9 volt battery this thing is loud! Definitely works as intended.

Loud.loud and loud. Sounds like a smoke alarm or heavy truck backup alarm. I connected the wires to the turn signal relay in my truck because I had the turn signal on all the time. Works great just had to wrap it with tape to calm it down a bit.

This thing worked great. It's exactly what you'd expect, making a high-pitched, slightly annoying, continuous tone. Pretty loud in my opinion. I installed it in my old car to beep when the turn signals flash and it was so loud I had to tape it on and it's still too loud.

Cheap! When trying to connect it to my truck, a red wire fell out of the device. I opened it up to see if I could plug it back in, but I couldn't because the wire was only 4 stranded and it broke at the solder joint on the board. The black cable also came loose while watching. Bad wiring! Save your money!

Great for a regular buzzer. It's a little cheap but works well. This was used as part of a basic circuit science experiment and for that purpose it worked perfectly. It makes a loud, very annoying, high-pitched noise, and a makeshift switch was used to turn it off. Good inexpensive product for basic educational purposes.
