It appears sturdy but it is not. The fire breaks so easily that you can't imagine. Only the alarm's decibels are worth it.

After 4-5 times, you lock it with closed eyes.
Good, user-friendly, functional.
It doesn't activate with the slightest touch, only if the disc moves and loses contact with the ball.

10 days later, Skroutz sent me a report - a suggestion for €30 cheaper (I think it was €96)

-Sturdy, the alarm doesn't go off with the slightest touch, the keyhole is tight and may need lubrication.
-It fits both small (scooter) and large (V-strom) bikes.
-The alarm activates as soon as I press the ball on the disc brake, afterwards it's not necessary to press it, it remains activated.
-I have various locks, this is the second ABUS lock I've purchased and so far I am very satisfied (I've had the first one since 2009).

Very good and easy to handle. I don't give it 5 stars because I would like the sound it produces to be a little stronger.

The lock is very good, easy to operate, and immediately hits as soon as you move the steering wheel a little!

It breaks easily, not loudly or for a long time. And it gives me the feeling that with two levers against it, it will open like a flower bud. I tried it because it was the only one that fit in my disc from best to worst. I hope it doesn't get tested.

Very good lock. Good construction. I have had it for a month now. The handling is easy. You just open and close it with the key. However, in order for the alarm to be activated, you have to "press" a ball that it has internally. The distance of the ball from the disc brake is half a finger, so you have to manually press it when you lock it. It fits well and seems reliable. The sound it makes is quite good. It doesn't seem like a lock that costs 40 euros though. The reason I'm not giving it the 5th star is the way it is activated, the distance of the ball from the disc brake.

Quality-wise, it appears very sturdy compared to another one from the same company that costs €40, so logically there will be a longer delay. Now, as for the way it locks and unlocks, it didn't impress me. On the Monster 796 that I use it on, the "tooth" that locks and unlocks doesn't have a large opening, resulting in scratching the disc plate. Also, when it locks, in order to activate it, a ball (theoretically from the disc plate) needs to be pressed, which with my disc plate has a gap of half a finger, causing it to catch movement, as the vibration is so strong that the disc plate hits the ball. If the ball was adjusted and lowered further, when I locked it, it would directly apply to the disc plate, so with the slightest movement of the handlebars, it would activate. In short, it is a good lock that hangs on the disc brake instead of being stuck on it, and in order to activate it, a significant movement of the handlebars needs to be perceived. On the other hand, the siren is 100db, but okay, it's not something amazing. It could be heard fine in an underground garage (with echo), but I haven't tested it in an open space
