    • It's loud and it works!
Review Image by K Man
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

    • Definitely kept them thief’s away
Now this has definitely kept my bike safe lol and also be advised it’s VERY loud lol. I also love how it looks discrete and can be hidden too which is awesome and same goes for the remote which is such a big help and for the material on the remote feels a little cheap which can be better but you get what you get for the price not saying it’s bad but I works very well which is all that matters ... show more

    • Bought this to try and make roommate stop snoring
So, as the title says, Im not using this for anti theft purposes but will review it a little anyways. I had stumbled across this while searching for wireless horns and being a little desperate, figured I'd give this a go. Now, before anyone yells at me and says I am being mean, let me explain that this person snores so loud I can hear it through two doors, a wall and my little radio. Its very obnoxious, it goes on almost all night and I put up with it for almost three years until I said no more!! I was even nice at first and muted the bell a little with cotton so it wasn't overly loud, but after a month of testing, the person literally slept through it and the horn had little to no affect; about a success rate of about 15% (this is calculated based on whether the snoring stops in relation to the button being pressed per night). SO, I took the cotton out, put it back in the box (to keep the decibels reasonable) and moved it a bit closer to target area. After testing for about another month, its been working approximately 85% of the time - While not perfect results, I am still truly thankful for the amount of success period!! I've even noticed that because I've been doing this consistently, the person coughs significantly less during the day (another annoying habit of theirs which I am positive is directly attributed to their chronic snoring). A few things about this item. If you're wondering how loud it is, its very comparable to a smoke alarm but slightly louder. If I were walking casually next to a bike and this went off, I would probably jump a few feet in the air. It will definitely get your attention for sure, no doubt about it. The alarm itself is difficult to open, but I imagine that is on purpose by design. All I would say about this is that the company gives you a plastic tool similar to a guitar pic to open; that should be replaced with an aluminum tool. The plastic one gets destroyed almost immediately and rendered useless. The batteries seem to be lasting quite awhile and Imagine they will for several months (I use this constantly so I am the best case scenario for testing that feature). My guess is that the remote will last about as long as your car remote before having to replace the button cell. The alarm batteries in the unit (3x triple A's) will probably last even longer. I can't complain about functionality too much, because I am using this for something completely unrelated for its intended use, but I do wish it was more direct and simple. I hate cycling through buttons to set features, and I to be honest I haven't even bothered because of it. That being said, it would be interesting if this company simplified a unit made to be a horn only model, perhaps similar to a bell on a bike to alert people. Although I don't really see that catching on. The price of this initially I thought was kind of expensive (keep in mind I am kinda poor though) especially because it was an investment that I didn't even know would work or not, but because of how much success I've had, I would easily buy another as it has been totally worth it. I can almost even see this being useful for anti theft around the house or if you wanted to scare someone off for following you etc. So while this is being used for something different, I still feel like the overall goal has been achieved; which is to make annoying people stop what they are doing. I can't test this product thoroughly, and am still in the process of testing longevity, but so far I give it 4 stars. ... show more

    • Great value for the price.
There’s obviously more expensive ones out there but it gets the job done. Volume is loud enough for my liking. Warning sound will go off first then the actual alarm if the item keeps getting moved. Deterrent an attempted theft on my motorcycle. Size is decent and small enough.

    • SOS feature sold it.
This thing is fantastic. Easy to install to the frame of the bicycle I ride, though it's a little too large to mount in a more discreet location. Personally, I prefer the frame given that if they successfully break through my locks, the alarm device is still on the bike and alerting as they ride it away, as opposed to an alarm lock that stays at the scene of the crime once they've broken through the lock or secured to a removable part like the seat, which can be removed quickly with a simple allen key. I love that it gives a warning chirp before fully alerting. Other products will go through a full alarm cycle before resetting every time they are triggered. Not only is it annoying, it's a waste of battery. I love that it has adjustable sensitivity levels. You can set it to a slight touch triggering the alert or someone actually having to handle the bike for it to alert. That range of freedom gives the ride the ability to tailor the alarm to their needs and individual situation. I don't love the plastic zip ties that came with it. The double sided tape made it easy enough to stick it to the frame and forget about it, but I spent an extra few bucks for stainless steel cable ties to secure it to the bike frame. I spent $700 on a bike, so I'm not going to secure it's alarm with 1/8th inch plastic zip ties. Just a nitpick, so no stars deducted. I LOVE the SOS feature. I have to ride a bicycle everywhere because I'm an epileptic. Riding a bicycle still isn't very safe for me, but it's safer for every one else that I don't drive. The SOS feature triggers when you take the bike below 45 degrees and then disables when you right it again. So, if I fall, the alarm triggers, I bike the bike back up and I continue riding. If I have a seizure, I fall, the alarm triggers, people nearby can hear and see that I'm in trouble and call for help. This, above all else, sold this product to me. No other alarm system factored rider safety into the equation. This product is loud, but not "I can't think straight" loud, more "I really wish this thing would turn off" loud. I have my doubts you'd hear it from too, too far away, but if you park your bike near a fairly well monitored area it'll attract attention. I plan to couple this with another piece of equipment that actually alerts me to tampering. 5/5 so far. Really, REALLY impressed with what I got for the price. ... show more

    • Instructions are unintelligible, but it works and is LOUD
Lost a star because the instructions are nonsensical. I had to pore through a few YouTube videos to figure out how to change its settings. And, it has an odd SOS function that I accidentally engaged while trying to set ringtones, sensitivity, and volume. I had to reset the device to factory default to get the SOS function to turn off. Lost another star because you can’t select the motion alarm’s ring tone. You can, however, set the ringtone for the “find me” button. I liked those alarms sounds better than the default set at the factory for the motion alarm itself. But, this thing is LOUD. And it is very inexpensive. I’m keeping it. I have an older car that does not have an alarm and this is a cheap way to arm that car. Plus, I’m thinking of using the alarm for backpacking trips. I’ll keep it in the bear canister and arm it once I stash the canister for the night. Buy it; the price is right. ... show more
