Wireless Remote Bike Alarm: 115dB Super Loud Bicycle Vibration Motion Sensor Siren Anti Theft Security System Motorcycle Alarm Waterproof USB-C Rechargeable Multipurpose Vehicle Alert Device

I've used this for about 3 months now and can say it's a good alarm for the price. It's pretty loud and has different sounds to deter thieves. It came with a few different modes of installation so you choose which to use. The battery is ok and have had to charge it a few times. I feel more secure with this on my motorcycle when I leave it in front of a store.

Great buy. Compact but loud. Key fob is awesome.

It's loud and works well.

Really nice 👍Works great 👍

I bought this item twice. It works extremely well. Its was very loud! I had to buy it twice because the first alarm remote did not stay on the holder attached to my bike. It fell off while riding my bike and I never found it. I bought a second one and the remote wasn't in the package. Now it won't work at all because I don't have a remote for it! Other than that it's a great alarm... I guess I would recommend not leaving the remote on the holder on your bike or it will fall off. I wish they would sell replacements for the remote piece.

Use in under my motorcycle seat. Still pretty loud. Kind of wish the sensitivity was higher. But overall, a great little deterrent.

Sometimes it doesn’t work and it is NOT WATER RESISTANT which is maybe why mine stopped working

Quite impressed works well have difficulty adjusting sensitivity
