This alarm is loud. Works as others has reviewed. Yes, I would recommend for others with expensive items you don't want easily stolen. Easy to attach to my ebike handle bars but not under bike seat.

This product is very loud and when I first turned it on it gave me a mini jumpscare. For its small size, it's very loud but works very well. There are a bunch of settings that you could use to either turn it louder or quieter and different sounds of alarms as well. The main thing I dislike though about this is that there is no easy way to take it off to charge the device, especially if you ziptied the device onto your bike or vehicle of choice. I just take a portable charger to charge it.

I would recommend!The build quality is solid and the alarm is SUPER LOUD!I’m not kidding when I say it’s loud; believe me, you don’t want to be next to it when you test it out lol.Lock was secure and very easy to operate.The remote was kind of bad quality as it looked 3D printed.

I got this after someone tried to break the lock I had. This thing is really loud and sensitive. Just activating the alarm sends out a very loud beep which I was embarrassed about the first time but now I like it let's others know it's protected. When I tested it out a small tap was all it took to send out a warning beep. 3 taps and the alarm went off hurting my ears standing next to it. This will definitely draw attention to it if someone tried messing with my lock again.

I couldn't get it attached from what they put in the package. I bought another one of the more common type, and it took a couple of minutes. But that's me, an RN in Critical Care. Good luck.

Hervorragender Alarm. Er reagiert wirklich korrekt auf Bewegung. Sehr laut. Die Fernbedienung fühlt sich in der Hand sehr hochwertig an. Mehr als ich erwartet habe.

Acerté de pleno, un gran precio para una gran alarma, muy configurable, en sensibilidad que es lo importante y en sonido, que es menos importante según mi opinión, pero bueno, eliges la más aguda que mejor se oiga en donde aparcas y listo.La baterÃa no la he gastado aún en un par de meses, con encendido y apagado diario, se carga por USB asà que te ahorras pilas y el tener parada la seguridad por no tener pilas para ello.El mando funciona lejos y bien, con función de encontrar el vehÃculo y doble aviso de encendido.La alarma en la mayor sensibilidad es muy muy eficaz sin falsas alarmas por vibraciones de motores o similar, pero si tocan, suena, a la primera, con avisos y luego alarma.Gran producto.

So klein wie diese Alarmanlage ist, so laut ist sie. Bei einer vorsichtigen Berührung des Fahrrades waren sie noch mit einem Laut. Falls man jedoch heftig an dem Fahrrad rüttelt geht es laut los. Ebenso wenn man das Fahrrad weg bewegt.

Cihazın ses desibeli harika, elektrikli tek tekeri çocuklar kurcalaması için aldım, hem alarm hemde yolda giderken korna olarak kullanıyorum. Kumandası olması harika.
