WSDCAM USB Rechargeable Bike Alarm with Remote 110dB Loud Volume Adjustable Wireless Vehicle Security Alarm System Anti Theft Vibration Motion Sensor Alarm for Car Trailer Motorcycle Scooter Ebike

Very loud. Easy to install. Provides a whole other level of peace when leaving my bike anywhere besides in my house.The sensor is sensitive. The wind will trigger it (therefore lock your bike up tight so it's not wiggling around!). Once, in the rain, the alarm just went off for no reason.This little device is absolutely perfect for all sorts of other things. You could leave it in the car, or your backpack whilst camping at night...I don't think I've even charged it once yet. And I use it fairly often. So the battery lasts a long, long time.It IS loud, mind you. Flips people out.I've bought two thus far, and have every intention of buying more.

Very good alarm

Ok so I've gone through a few of these wireless alarms and so far this one is by far the best. It's the loudest I've heard from an alarm the remote works from a good distance away unlike some others I've had and battery is excellent for a rechargeable its been a week alarm on and still working the best part is once you mount it you twist it to remove it from the mount for easy recharge and twist it back on its great in very happy with this

Is very compact I have mine taped hidden on the frame of my ebike also comes with a plastic ring style mount if you want to install it on your handle bars easy to install and easy to take off its twist mount just rotate it to take it off the mount to charge with a USB charger then twist back on the mount

This was an easy and affordable way to add some security to my motorcycle. I stuck the device under my seat and it is still plenty loud enough. The main issue that I have with it is that the arm/disarm sound is significantly louder than the actual alarm. Everyone in the neighborhood can hear when you activate it. I'm not sure why they made it like that. Otherwise, a great value.

Great equipment. Small, easy to install. Great level of sensitivity.

Not the the best but the best for the price.Loud alarm and easy to hide.

I purchased this to avoid my catalytic converter being stolen. I installed it magnetically on the undercarriage and even at its highest setting it will not go off unless the truck drives away or for some reason you close the bed of the truck. I still haven’t found a good location where this might work to prevent such a theft. It does appear to be really good quality and since it doesn’t take batteries, I assume it will last a little longer than the average motion sensor unit. I don’t think it’s a bad product, I just think the truck is too big. It’s hard to move it around to trigger the motion sensor. I’ll post an update if I can find a better location.
