Faburo Disc Lock Motorbike, Motorbike Alarm Disc Brake Lock 110dB with Reminder Cable, High Security Anti-theft & Waterproof Motorcycle Disc Lock for Motorcycle Bike Moped Vespa Motocross Accessories

Very impressed, esp. as this was about 1/3 the price of my last one from a motorbike shop. The alarm is loud, it seems well constructed, comes with spare batteries & other accessories, fits well on the disc in the wheel of my Vespa - and damn these are so much more convenient than putting on & taking off a big bulky chain, esp. in winter when said chain gets wet and grubby. I have only had it for a month or two, so cannot comment on its durability, but so far I'm happy with it & surprised at the quality given the price!

So far so good. Its pretty loud so let's hope it does the trick and helps prevent my bike from being stolen. I had 1like this before from a different seller and when the rain got to it the alarm on it stopped working so ended up with a disc lock that was silent even though it said it was waterproof. Let's see what happens with this one. Seems a sturdy device.

Alarm is loud and very sensitive, which is great. Only downside is the locking pin is small in diameter making it rather easy to cut. I would only use a product like this as a secondary deterrent.

Yer it’s a decent disc lock not to sensitive that it goes off in the wind but if you proper tug at it the alarm will go off and it is loud , so all in all pretty happy with this one

The alarm is brilliant, it's quite sensitive and very loud. We'll made little disc lock

Very good lock, however if the seller could contact me regarding this I have not only used for 2 nights and on the second night there was a buzzing from the alarm and got woken in the morning by neighbours on both sides as the alarm buzzing was very loud.

if any one even move or touches my bike it warns them first then very loud - and where I live too if someone managed to get through the back door of house and it will be loud enough for everyone to hear - I have not used it in the rain yet though - also I still recommend locking your bike to something as well with cable and u lock - but that disc lock alarm is quick and easy - way better than I thought

Is definitely not the strongest metal but looks and feels very high quality and quite imposing for the price you cannot go wrong I would highly recommend
