  The alarm belongs to the category of vibration alarms only. These alarms contain a circuit with a two-contact mercury switch (like the component of a resistor) that cuts off the two contacts with the slightest vibration, and the integrated chip (controller) detects the interruption and activates the siren.
  Of course, this specific one does not have exactly a mercury switch (costing €1 retail) but a similar cheaper component that does approximately the same job as the switch, resulting in needing space in the box to be able to vibrate. The construction box is very small (with relative pressure I placed the 9V battery inside and it does not come out unless you open the box to pull it out), which makes the alarm unresponsive to the slightest vibration, in other words, unreliable. The only positive is that it is remote-controlled. I was not at all satisfied with this. For a few euros more, there are alarms for bicycles, motorcycles, or scooters that have a rechargeable battery and USB charging and many more functions and are quite reliable. In conclusion, I do not recommend it for the safety of your two-wheeler.

  In a week it broke. I opened it and due to the vibrations of the bike (city bike), the cable had come loose in the speaker. Its sensitivity, although initially good, does not work properly after my intervention. In general, you get what you pay for, but I wouldn't buy it again.

  I have put it on my machine and it works perfectly, and the sound it produces is very deterrent.

  It works great for the bike,
  the only drawback was the high battery consumption,
  but with a simple switch (on-off) that I added, that was also solved (from lasting 2-3 weeks it reached 6 months and !!!)

  I like it, it activates immediately, it is definitely a security measure that you want to have on your bike/scooter, it produces a satisfactory sound, not very loud though, but it can scare someone who wants to steal it

  A useless product, it never worked, except when I put the battery in and heard the siren (on the street with all the noise, I doubt anyone could hear it...)

  Small in size with a relatively strong (alternating) siren sound. Its main problem is its sensitivity. It requires intense vibration to activate.

  Edit:
  After using it for about a month (having to activate it 5-6 times for durations less than 10 minutes), the battery drained.

  For the price, it's good. It does the job for a bike, but it shakes and scares the other person riding with you. I don't know yet how long the battery lasts because I read that it gets consumed relatively quickly. They sell it a bit expensive compared to the fact that you can find it for 5 euros from China. You just need to be patient for a month. It depends on how much you really want to get it.
