WSDCAM USB Rechargeable Bike Alarm with Remote, 110dB Loud Wireless Anti Theft Vibration Motion Sensor Vehicle Security Alarm System Waterproof Bicycle Trailer Motorcycle Alarm

I charged it out of the box and it still works perfectly, loud

I use this alarm on my bicycle. It is exactly what I wanted for my bike. The sound of the alarm is very loud and effective. If you are not expecting the sound of the alarm, it will definitely startle anyone that does not know about it. Great way to scare off any thiefs. Additionally, I reached out to the seller because a peice of the alarm mount that attaches to the bike had broken due to me over tightening it. I was expecting them to just replace the broken peice but they sent me a new alarm with all of the peices! That was very generous and very much appreciated. While in conversation with them about getting a replacement, they were very professional and respectful. I highly recommend this alarm and buying from this seller. Thank you for the great product and help with my situation! :)

This works perfectly

Hasta la fecha funciona de maravilla, se escucha perfecto a distancia y su censor es sensible perfecto

Nice and load easy to charge and take on and off
