SOLID BIT OF KIT
Very sturdy and super loud! Just what you need. Had a similar model before but nowhere near as loud. Easy to install pull tab out and it’s ready to put wherever you want it. No idea how long battery life is, solidly made quite heavy for size.

Great piece of kit
For a cheap little alarm this is great tells me when the local cats are on my scooter which is one of the reasons I bought it to stop the little blighters from getting under the cover and scratching my seat and also it’s a bit of a deterrent from light fingered people has different sounds and gets louder to her your attention well worth buying .

Windy tarp dont bother, inside garage amazing
This is actualy pretty good, lifted seat up popped it with 2 x zip ties under seat, easy to alarm, with the fob, if bike moves alarm goes off exactly what it says on the tin, works perfectly, now for the downfall if its windy it sets it off if you have it under a tarp/cover, that said if it's in a garage shed ectthis is awesome

It does everything it said it would. The at third from the most sensitive setting it will give a warning siren if I close my front door too hard. The battery lasts a long time, and it is very loud. The remote works well, and configuring it was easy. I haven't tried it on a bicycle, but I am thinking of installing one on my motorcycle.
