Security 999 anti-theft disc padlock with alarm 120 db a + Warning, High Security CLASSE SRA Approved, 14 mm Shaft, Made in EU

Great product. Looks solid. Alarm quiet laud. Unfortunately not too loud when covered with bike cover. With other securities this will do the job.

Superb build quality! Not too sensitive (which is important), and you don't have to use the alarm as you get an option to arm or not!

I'm using this disc lock on my Kawasaki Versus.It's easy to operate and so far no false alarms. Its sturdy and well made too.Excellent device. I might try to use it on my bicycle

So far it's working okay. I believe that it will slow down a would be thief's progress. The only issue is when locking. The pin is large so It can be a bit awkward trying to arm the alarm when closing it, as it has to be double pushed to set the alarm and can move off the gap in the disc by the second push. The sound is loud, it could be louder. I find it hard to believe that spending £95 on a lock and it doesn't even have a spring cable supplied.

Very strong and can’t be forcibly broken like cheaper ones, alarm loud to deter and remind you it’s on if you try to move.

best lock out there by far easy to put on ta scooter and it is solid and very loud..

as in the description

Good strong lock for the money.

Es bastante robusto..y bonito ...su eje de 14ml no entra en el disco trasero.pero tenia eso claro ..es por eso que se lo puse en el piñón de arrastre.. en general buen producto

I bought this disk lock with alarm and bought a mount from another company, but it worked even better than I could imagine. Mounting was easy using the provided hardware. I settled on the perfect spot that keeps the lock safe and completely out of the way when I’m not using it. Almost looks like it was supposed to be there. The lock and alarm work amazingly well. I can use it on the disc as intended or can even arm it on the mount and just use it for its alarm only. If anyone touches the bike while it armed it warns them, then it screams its head off. Absolutely love it. Just buy it.

Molto solido e ben costruito e pure il sistema di allarme funziona ed é tarato molto bene con un sonoro davvero potente al pari di un antifurto da automobile.

1 yıldır kullanıyorum, alışmam biraz zaman aldı. Scooter tarzı motorumun diski bu kilit için biraz küçük olsa da takabiliyorum. Motora kedi çıkmaya çalışınca bile alarmı çalıyor 6 kere, kilidi takmayınca kediler çıkıp tüy ve koku bırakıyordu, koltuğa zarar veriyordu, iyi bir önlem oldu. Hırsızlığa karşı da bu hassasiyet yeterli diye düşünüyorum, umarım başıma gelmez ama içim rahat.

Bonne qualité. Je n'ai évidemment pas essayé de le casser, mais il semble très solide, et est bien fini. l'alarme intégrée fonctionne bien et bip dès qu'on touche la moto. on ne risque pas d'oublier de l’ôter au moment de partir. Le mode sirène est plutôt puissant pour un si petit module. Très content de mon achat pour l'instant.
