Bicycle Alarm with Remote Control and Motion Detection
A
The ringtone is really loud^^
I just received it so I'm not sure, but the sensitivity seems to be off.
I guess I'll have to try it as if I were stealing it directly^^
I will leave an additional review later.

I had the A2 from the white box and it was very good and quite sensitive to vibration. This Rockbros one seems to be the same but a little different; the ring volume is quite high, and the vibration sensitivity seems good at level 3, although the other one was better. The battery is still being tested, but if it lasts about 30 days with about 12 hours of use per day, that's fine. I recommend it for use on motorcycles and bicycles.

He does his job really well, highly recommended 👌🏽 ☑️

The sound is ringing and echoing.
The question is how long it will last...
C
This is my third purchase. The sound is loud and the performance is good, but one broke after 6 months and the second one broke after 2 months. I hope it's more durable.
K
This is my second purchase. It broke and didn't work, but I tried it again and was satisfied, so I bought it again. The sound is really loud.
E
It's really small and the product quality is good.
R
I haven't installed it yet, but I trusted the product and bought it. ^^

I previously purchased and used this product, and the quality, design, and performance were all perfect, so I am repurchasing it.
M
The quality is top-notch. There seems to be no other product with such a great design.
J
100% recommended as indicated in the download!
D
The horn doesn’t produce sound the way i want. Instead of responding to how much i press it, it plays a constant, continuous sound as if it’s a recorded tone. I want the horn to react to my pressure a short press should give a short beep, and a long press should give a continuous sound
A
It looks high quality, just need to test it.
M

It sounds very loud and is easy to set up, I recommend it.
T
I love it, it’s very sensitive. if i just touch the bike seat, it emits two warning beeps, and touching it again triggers an alarm. it’s also very easy to install everything and adjust the volume. the package arrived open and damaged, but otherwise, everything was fine.
