  • It's loud and it works!
There are already a lot of photos and videos of this product so I will not beat a dead horse. I can see where there could be some problems with placement of the alarm. If you were to put it in a place that gets more vibration or unmitigated shocks, I could see it being damaged. However, if you think critically about where you place the it, you should not have any problems. I installed this on my ebike and it has been working great. Too good, sometimes, like when I forget to turn it off before unlocking it from the bike rack or going to jump on it to take off from behind my house. Everything works very well though I have not gone in to change settings at all because the first time I pressed any button it was the emergency button, in my bedroom, and it was earsplitting. Seriously the neighbor upstairs probably thought... I don't know what I would have thought but it would have woke up the whole house and my ears were ringing. I have seen the issues some people have with the fob. Maybe they will eventually make one a little stronger so that you can put it on your keys, but for my purposes, I did not even really want this on my key ring and I had a better solution just sitting around anyway, which I will post a picture of. I just wear it around my neck but under my shirt when I have the ebike with me. Works great for me. The price was great for what this thing does. If you get a good lock and have this thing armed, I mean, as soon as a person would go to position their bolt cutter or angle grinder, this thing will start making some noise... very loud noise, and you really have to be in the hood for this to go unnoticed and for it not to scare the hell out of them. When I go into a store in the day I just park the bike in a car spot and arm the alarm. It ain't going anywhere. Try out a flat lanyard like in this photo for the fob and it should not break. For me, this is an easy five star item. I waited a little while to write the review just in case it broke early on but I have about a hundred miles on the bike and everything is perfectly cromulent. I recommend it. Thank you. ... show more

  • Excellent Product...but know how to handle dead battery in the remote...when it happens.
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. ... show more

  • Don’t trust other $10 bike alarms
The range is very incredible, bike was in the shed and I was in THE HOUSE and alarm still went off when clicked a button. Very nice loud product at 113db. Not too big either and really easy to zip tie onto bike. Batteries last for about a year which is really good too. Don’t trust those $10 bike alarms, GET THIS ONE! ... show more

  • Just like a car alarm
Ebike thefts are rampant in my city. This helps deter thefts. Really loud and works just like a car alarm.

  • It’s ok
Not as sensitive as I would like. I used the max sensor setting but you need a lot of movement for it to go off. The instructions are not that great either. Just a deterrent for my car. Loud enough though. I just Velcro underneath my bumper whe I need it.
