A good cheap car mod for anyone without an alarm
Bought these to wire in as a “lock” alarm that didn’t exist on my Toyota. Works great to add a remote lock beep to the car and good for many other uses I’m sure. I wired 2 in a series and hid the wires with the factory wire loom on the firewall of my truck. They’re pretty loud and no issues with reliability. A good cheap car mod. I saved the 3rd alarm as a backup in case one of the other 2 ever fails.

loud beeper
Loud using 12V battery! Not excessively loud, but it can be heard from about 50 feet away. Would be nice if the wires were larger gauge to make connections easier. The wires are about 20-22 gauge solid wire which requires soldering the wires to connect them to anything. I needed to connect with spade connectors so I had to solder the wires to the connectors before I could connect to the power feed wires. I have only had them installed for about a week so I am not sure how long they will last, but for the price and getting three it was a good deal.

Great little buzzers!
These are seriously loud - at 9V they put out impressive volume, definitely living up to the 90dB rating. Perfect for alarm projects or anywhere you need an attention-grabbing sound. The 3-pack is a nice bonus too. Would definitely recommend for any electronics projects that need a powerful alert sound.

Used as a tester beeper for boat DC.
Really simple beepers. Worked well. Good price.

Sounds exactly like a golf cart reverse tone!
These are loud and sound exactly like a golf cart reverse tone! We installed one in a water bottle with a switch and 9V battery to hide in a friend’s golf cart. She thought her cart was stuck in reverse, and a mechanic friend had to find it for her! This lasted a long time on a 9V battery and worked perfectly!

not very loud
listed at 95dbs which is loud. At 12vdc you can just hear it, not loud at all.

Does what they're supposed to do
I didn't specifically buy these for backup alarms however they do work well for that... I wired one up with alligator clips so I can trace wires on lights in vehicles without having to run back and forth from the front to back of vehicle, very handy... Especially for the price
