Wsdcam 113dB Bike Alarm Wireless Vibration Motion Sensor Waterproof Motorcycle Alarm with Remote

Better than expected. I’d buy this for anything I have that would need an alarm. Only thing I wish is is that there were more sound options for the alarm sound and instant alarm when set.

Very loud it surprised me how loud it was my ears literally still ringing right now. Recommend great price.

Easy to install and easy to use

I wanted to give this alarm a 5 start rating: however, the lack of information on what might happen when the battery in the remote goes dead, made me choose a 4 star rating. First, all in all, this is a top-notch product and I highly recommend it. It is loud, it can be adjusted (sounds and level of sound) and it is waterproof. I have three of them (1 for my RV door and two for my electric bikes). The only issue I have had occurred 1 year into my ownership of the alarms. I touched my bike and the alarm went off even though I did not set it to do so. I tried using the remote to shut the alarm off, but, even though the remote light came on it would not shut off the alarm. Every time I tried to touch it, the alarm went off and the remote was useless. After having to research this, a You Tuber had the answer. Even though the remote light came "on", when pressing "set" or "off"...the battery was too low to send a signal to the alarm. So, I went about trying to get the remote apart and at first it seemed like I would break it, as the silver part seemed to not want to separate. With some wiggling it did separate and I could change the battery. BUT, now came the other part of this problem...the stupid battery is NOT an AAA battery (like in the alarm) and it is not a standard Circle Battery (like in most other electronics)...IT is a 27A battery. Some crazy miniature AAA battery. So I had to order it on Amazon. It fits nothing else that I own...just this alarm remote. With this problem solved, I suppose this alarm needs a 5 star rating or higher. Seller was great and the price was reasonable.

This alarm is loud just as i need it to be. It is currently strapped to my ebike. I love how it is easy to install.

Works great on Honda navi. Probably too many functions but it's easy enough. Sounds loud and electronically nice and sensitive.

BUY IT ! It's the best investment I have made in a while in regards to my motor scooter. Here in Colombia, moto thefts are rampant, and I sleep much better having this. If another person or bike hits mine in a parking space which have no lines, I know it immediately, and if someone leans on or tries to move my bike, or even messes with my luggage box on the back, everyone around knows it. A great investment for very little money. I have purchased multiple units for my wife's and friends' motos over the past few years.

Love it but battery died in less than a week! It says will work for a year.
