They appreciate its security features, with one customer noting it serves as a deterrent against bicycle theft.

    The media could not be loaded.
    I was a little skeptical about ordering this Alarm being that it is inexpensive. But after ten minutes of installing it with zip ties under the seat of my very expensive folding travel scooter all doubt was replaced with true joy! This alarm works fantastic, the remote transmits from a LONG distance and the alarm sound is incredibly LOUD, and very sensitive on the highest sensitivity setting. (see my video) You can turn down the sensitivity setting, it has settings between 1-7 for sensitivity. I also was happy to find that the alarm was very consistant. I armed it 10 times and then "wiggled" and bumped the scooter and each time the alarm triggered.
    This alarm will give me piece of mind when I leave my scooter unattended, like on a sidewalk outside a shop or store that I cannot get into while riding it. Before I always had to keep an eye out for the scooter and worried someone would take it. (It weighs less than 50 lbs.) The only negative is that the zip ties included are "brittle" and one broke when tightening it, so I chose to use better quality ones that I had in the garage.

    It is so refreshing to find a product that "does what is say it does." especially since it is inexpensive and made in China.

    it needs to be used unenclosed, outside whatever it is protecting. if it is touched it makes a hell of a racket. Stick one on your laptop, if you like to leave it on the table when you go to the barista for a refill. Put one on your bike when you park it outside by the door.
    It goes off briefly if the item is touched, and non stop if it is touched again. You turn it on or off with a remote. All it does is make a racket and you have to be there to hear it and react to the disturbance. For the money it is somewhat useful. But if your item gets carried off while bleating it's head off at 120 DbA, you're out of luck. if you put a lojack on it also, located someplace not obvious, that might be a great way to trace it and retrieve it if the thief stops looking for alarm components after removing the noisy one.

    Works as described but not super loud. If placed under a motorcycle seat or under the tank, it's audible but range is shorter than desired, ~100ft before it becomes background noise.

    I installed the alarm inside a two wheeled tow behind trailer to protect against theft. I turn the alarm off when I will add to it and when getting ready to tow it. Otherwise the alarm is on and I set the alarm sensitivity so that it will only sound off if the trailer is being hitched up to a vehicle, or jostled around by hand.
    If a local bear or raccoon moves it around enough it will also alarm, and I can remotely disable the alarm and reset it when the animals have departed. A very good item in my opinion.

    I bought this to hopefully deter someone from stealing the catalytic converter from my prius. I put it under the hood so the sound will be piercing, but in a place where the thief wouldn't be able to find it. Pros: it's very loud and cheap. Cons: It's very sensitive and gets set off almost every time a trash truck drives by. I'm sure it annoys my neighbors when it goes off, but I don't care. I mainly have it to deter someone who doesn't want an alarm blaring at 3am while they are up to no good.

    5.0 out of 5 stars It works and it's loud
    Reviewed in Australia on January 14, 2024
    UPDATE: So after 4 months use, the original batteries are still in the unit. Buying another as a gift.
    ***************************************************************************************************************

    After my car got broken into, I decided to get a car alarm installed but I needed to do some research first. In the meantime, this device would give me some coverage. It's relatively small in size easy to set up and hide anywhere inside your vehicle. For me, the sensitivity is just about right. Once activated, hard closing of the car door will set it off. It's not perfect but for the money, it's very good value for security.

    It takes 3 AAA batteries and as I've only had the unit for a week, I can't comment on battery life. I'll update this later once the batteries need replacing.

    I am using this product for my car since last two weeks. I tied this product inside the car bonnet (Near to wiper but not accessable from outside). The sensity level of the product is really nice. It can even detect the engine turn On/Off. But i am little bit disappointed with the bulit quality of the remote (Feels like toys remote). If company can provide the remote with a rubber pouch it will be much better. Overall i liked this product on this price tag.

    5.0 out of 5 stars Bin sehr positiv überrascht - Einfache Anleitung zur Programmierung in der Rezession
    Reviewed in Germany on January 29, 2020
    Habe mir diese Alarmanlage für mein Quad gekauft. Da sie sehr klein - jedoch laut ist, bin ich vollkommen zufrieden.
    Das einzige was ich schade finde, ist das, wenn der Alarm losgeht - verschiedene Alarmtöne hört.
    Hier wäre es schöner gewesen, das man einen Ton "fest" einstellen kann.
    Programmierung einer zusätzlichen Fernbedienung ist kinderleicht und funktioniert tadellos.
    Für den Preis sollte man aber nicht meckern!!!
    Nachfolgend noch eine Anleitung bzgl. programmieren der Fernbedienung.
    ---------------------------------------------------------------------------------------------------------
    FERNBEDIENUNG
    • Schlüssel aktivieren (der erste Schlüssel)
    • Taste deaktivieren (die zweite)
    • Klingelton-Taste (die dritte)
    • Programmtaste (die vierte)
    Taste aktivieren:
    Einmal drücken, der Host-Alarm geht in den "aktivierten Modus". Der Alarm
    wird ausgelöst und ertönt, wenn Vibrationen oder Bewegungen festgestellt werden.
    Taste deaktivieren:
    Drücken Sie diese Taste unter "Aktivierter Modus". Der Alarm wird
    abgebrochen und kehrt in den "Standby-Modus" zurück.
    Wenn ein Alarm ausgelöst wird und klingelt, drücken Sie diese Taste einmal. Der Alarmton wird
    sofort beendet.
    Klingelton-Taste:
    Drücken Sie diese Taste in einem beliebigen Modus oder Zustand. Der Alarm
    ertönt sofort. Zusätzlich stehen 6 Arten von Klingeltönen zur Verfügung.
    Programmtaste: Diese Taste ist nützlich, wenn Sie mehr Fernbedienung hinzufügen müssen.

    EMPFINDSLICHKEITSEINSTELLUNG
    1) Halten Sie die zweite Taste etwa 6 Sekunden lang gedrückt, bis die Anzeige immer leuchtet.
    Drücken Sie anschließend einmal die erste Taste. Der Ton fordert die aktuelle
    Empfindlichkeitsstufe an.
    2) Drücken Sie die erste Taste erneut. Die Empfindlichkeit sinkt auf die nächste Stufe. Drücken Sie
    erneut. Die Empfindlichkeit sinkt dann, bis wieder die Empfindlichkeit der ersten Stufe erreicht
    ist.
    3) Wenn Sie dann die zweite Taste einmal drücken, wird die von Ihnen gewählte Empfindlichkeit
    gespeichert.
    Aufmerksamkeit bitte:
    Die Standardempfindlichkeit ist die größte, es gibt insgesamt 7 Empfindlichkeitsstufen.
    Jede Empfindlichkeitsstufe hat einen sofortigen Ton, einen Ton von hoch bis niedrig: do, r, mi, fa,
    suo, la, xi

    SOS-FUNKTION
    Drücken Sie die dritte Taste einmal. Der Alarm ertönt sofort.
    Wozu dient diese Funktion?
    1) Finden Sie Ihr Fahrrad / Auto sehr schnell unter vielen Fahrrädern / Autos
    2) Wenn jemand in Gefahr ist oder Hilfe benötigt, kann die 115 dB laute Stimme die
    Aufmerksamkeit anderer auf sich ziehen.

    Wie kann ich eine zusätzliche Fernbedienung mit einem Alarm
    verbinden?
    1) Drücken Sie die zweite Taste der Originalfernbedienung einmal, drücken Sie die vierte Taste
    das nächste Mal lang und lassen Sie sie nicht los. Der Fahrradalarm ertönt zweimal lang. 5s später
    ertönt ein kurzer Ton.
    2) Lassen Sie zu diesem Zeitpunkt die vierte Taste los und drücken Sie dann einmal die zweite
    Taste der zusätzlichen Fernbedienung. Der Alarm ertönt "Bi Bi", was bedeutet, dass das Pairing
    erfolgreich war.

    Wie wähle ich einen Klingelton aus?
    Drücken Sie die zweite Taste einmal, und drücken Sie dann die dritte Taste, um den Klingelton zu
    ändern und auszuwählen. Es gibt 6 Klingeltöne. Der Alarm speichert den aktuellen Klingelton.
    Wenn Sie die letzte Taste drücken, wird der ausgewählte Klingelton durch einen Alarm ausgelöst.

    Batterie schwach anzeigen
    Wenn der Fahrradalarm schwach ist, ertönt beim Drücken der Fernbedienung ein leiser Ton "Du ..
    Du"
    Wenn die Batterie der Fernbedienung schwach ist, ist die Kontrollleuchte schwach.

    Ich hoffe, mit dieser Anleitung kommt man zurecht und ich konnte damit dem ein oder anderen helfen.
