Jamieâs Reviews –
Great deterrent
Perfect for my mobility scooters. This is my third set of same brand. They last a very long time. Sold a scooter with one of these attached and buyers were very impressed. The other two are still on boot and outdoor scooter. Alarm sounds when warning buzzers are ignored.

Good alarm for lots of uses.
Very good loud alarm. Seems OK so far.
MICO’S TECH ADVICE –
Very valued price
I bought this wireless bike security alarm for my new bike as my old bike got stolen. I had a different but more expensive alarm on the other bike, but it did not seem to work well at all, and the battery was very limited lasting and so it didnât last long enough. It had a lifespan of around 1 to 2 weeks before needing to charge. THIS However, was much more simpler to use and the seller claims it has a long battery span and so this is what had attracted me as there are limited alarm devices available on the internet to purchase.The price I paid for this alarm was moderately cheap and worth the bargain for me. If I was to choose to buy another bike alarm itâd be this one itself. You can also be flexible when using this gadget, you can change the bell sound when using it to warn or get people to come out of your way.Sound. The sound was exceptionally high in my view that if I was to use in a busy place like a supermarket it would attract so much attention from the public which is a good thing in my view.The only main dislike was the power technique, it uses simple non rechargeable batteries to charge and removing the gadget from the bike means you have to buy new cable ties and sticky pads so it could be time-consuming and a waste of resources. If it had those holding mechanism it would be more useful.I hope my review was helpful.

Nice, simple and fantastic value!
Fitted this alarm to my MT-125 motorbike. Didn’t want one that would drain the battery on my bike so I opted for a self contained unit.It’s simple and easy to use. There’s YouTube tutorials on how to set the sensitivity and ringer (just search the model number ->KS-SF22R<-). You can also test the alarm to hear which ringtone you picked and to see how flat the battery is (is quieter the lower the batteries).Only con is the batteries that come with the alarm aren't fantastic and I will be changing them for Duracell at a later date. No biggy though, you pay for the device and it's well worth it.TIP:I've got 2 locked slots on my bike, one requires the driver's key and the one is a ratchet screw. I would suggest to hide the alarm in an area that doesn't require the driver's key because the locks are easily picked and not everyone carries round a torque wrench around.Will update review if there's any issues...

Perfect for my requirements
I wanted an alarm for my motorbike while it’s parked outside the house at night. I’ve previously had a couple wired alarms, both of which had failed after a year or so, so I thought I’d give this a go and have it mounted under the seat. It’s not as loud as the wired ones, but is certainly loud enough to wake me and is sensitive enough to pick up any small movement. I did have to turn it off during storms Ciara and Dennis, as it kept triggering in the highest winds. Along with a couple of very heavy duty locks, it’s an added deterrent against the casual scumbag.

Loud!
Really great product. Gives me great peace of mind when the bike is locked up at night, good and loud. The only downside is that it is rather loud when you deactivate the alarm also- It would be nice to have the option to quietly deactivate it as sometimes I set of riding early in the morning and I hate to think Iâve woken my neighbours up.

Exactly what you expect
Purchased (28 February 2019 | £13.99)Do bear in mind this is not a high end security system, this is just a deterrent.Its purpose is to try and make someone change their mind about stealing your stuffIn summary, it is very loud, very easy to use, very easy to set up, made of plasticThe plastic it is made of is not the strongest, you could drop it on concrete and it would be fine, but a hammer would put this thing out of action pretty quick if a would be thief wanted to silence itIt does come with batteries, zip ties, and adhesive pads so you shouldn’t need anything to attach this to an object – unless it needs some other sort of equipmentI can’t comment on the durability or the water resistant properties of it yet as I haven’t had it long enoughIf there are any issues I’ll update my review

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.

Très bon achat.Correspond à mes attentes

super teil!nachdem ich sehr von abus enttäuscht wurde und von einem no name bremsscheibenschloss mit eingebautem alarm ebenso, habe ich mir mit nur noch geringer Hoffnung diesen China-Zwerg bestellt, der 3db mehr haben soll, als die beiden anderen Kandidaten.die Fernsteuerung könnte natürlich hübscher sein und die Befestigung am Motorrad nicht mit plastik-, sondern metall-Kabel Bindern.aber die Alarm Funktion kann sich im wahrsten sinne hören lassen – das ding ist laut!auÃerdem funktioniert die Fernsteuerung einfach. kein gefummel mit einem schlüssel oder sonst was.an meiner Sportster mit schwarzem rahmen und motor ist das teil komplett unsichtbar – bis es los geht.dann kann das keiner mehr ignorieren.die unterschiedlichen Lautstärken und Sounds hab ich nicht ausprobiert. aber im Grunde braucht das auch keiner.definitiv zu empfehlen.
