after 1 year of use, the navel disconnected completely.. unacceptable for so much money, it happens to others too from what I read..

It looks quite solid as it is heavy but it triggers too easily when removing it there should be a way to disengage the alarm when using the correct key. It does not sound too loud though

Great lock and the alarm sounds satisfactorily. The only downside is that I haven't found a base to carry it.

I have been using it for a few months on a daily basis, very good construction.
As a disadvantage, I would say that the sound could be louder.

After 5 years of use, the buckle broke in my hand. Obviously sturdy, but incredibly expensive to break so easily.

WARNING IN USE!!! It does not work for all disc brakes. Before purchasing, test it! The alarm is very good, the construction is the same.

By far the best anti-theft disc brake. It has a large thickness, so if a thief targets the bike, they will have to cut through the disc rotor and not the lock, which takes time and discourages them. At first, I had difficulty removing it because of a tooth on the key, but now I've learned how to do it in just 30 seconds. I have been using it daily for 4 months now. NEVER leave your bike without a lock.

As construction is very sturdy. As for the security it provides, I believe that with a stronger siren it would scare someone off. The current siren is very mild, considering that it wouldn't be heard in a busy and noisy city. Not to mention someone on the second floor with closed windows. Also, its weight and size do not make it portable, so it needs to be put in a backpack for travels as the sensor will be affected by the vibrations in the trunk.
In summary, it loses 1 star due to the weak siren and the relatively difficult transportation for everyday use.

Very good lock, I believe it is the best in its category. Very good sensitivity of the alarm, which of course doesn't hurt your ears but is honest. Heavy and sturdy, it doesn't fit on all disc brakes, better to try it before buying. It's worth its money, I would buy it again

Bought it 2 years ago, almost daily use on a scooter mainly but also on a motorcycle.
Initially, the black protective cover (wheel) that gives access to the key fell off.
We put it back on, but it kept coming off!
10 days ago, as I went to lock it and remove the key, it got stuck, and the lock mechanism broke, the padlock remained locked on the disc plate!
After a while and after forcibly breaking it (what you see in the photos), I managed to remove it!
I took it to the store where I bought it, they sent it to the dealership, and their response is that it cannot be repaired!!
A lock worth almost 200 euros!
In terms of security, I consider it top-notch, a heavy lock, but be careful to test it before buying it, it doesn't "fit" all disc plates!

Sturdy construction, heavy, with very good sensitivity - just right - for the alarm. It appears resistant and impervious to common means. Two keys are included, one with an integrated flashlight and one standard, as well as a carrying case. It combines very cleverly with the corresponding Abus Granit Detecto X Plus 8008 12ks Loop Chain (sold separately)

The best lock out of all if you want maximum security is a one-way sturdy construction I bought it for 165 euros...
