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.

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.

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.

LOUD, EXTREMELY LOUD
This works great! I definitely feel better knowing my motorcycle has an OBNOXIOUSLY LOUD and SENSITIVE alarm while it's parked outside :) The remote is a good size, slimmer than it seems, the actual alarm is on the bigger side, but it still fit unseen!

Just got it
Easy to set up. 3 different alarm or signal noise. Cool remote that connects to a key ring. I’ll come back if something’s wrong but I am grateful thank you. (Can make a noise if you’re looking for your ride, or you can use it as a honker thing) get a hamburger bell or whatever fits you instead to alert oncoming people. I just cleaned my scooter and picked it up to carry it in and the alarm I forgot to turn off made the alert like it was being stolen.. so IT WORKS! Idk how but whoever made it is smart

Excellent alarm for your e-bike or scooter!
Wow! This alarm is awesome! It’s loud enough to scare off anyone trying to steal your e-bike! If you have a very expensive bike or even a scooter… you need to purchase this right now!

A great Alarm detterant,works a treat!
A good detterant for anyone thinking about breaking into my toolbox. It's very loud and works excellent,I have mounted it under my ute toolbox lid near one of the locks and any vibration or tap will set it off You can adjust sensitivity and volume of siren but I found it just perfect for what I want it for. The remote is small and works from approximately 15-20m away which is fine Overall it's a great alarm which will make anyone think twice from trying to steal my tools You could also mount it on a motorcycle under the seat or even for a shed door where movement or vibration will set it off A great purchase,very happy

Nearly gave me a heart attack 😂
Absolutely brilliant little alarm. Easy to fit, really sensitive and ridiculously loud for the size of it. I’ve forgot it was armed a few times and nearly jumped out my skin when I touched the bike 😂 Definitely does the job and gives good peace of mind when leaving the bike anywhere.
