Target TL112 Alarmed Cable Lock - High Security Cable Coil Lock with 110dB Siren Alarm - Bikes, Bicycles, Scooters, Garden Gates, Securing Helmets with Motorcycles

Good quality and very safe. One of them makes a strange sound sometimes when it's the alarm setted up and i have to restarted it.

The alarm is very sensitive and loud. Big, chunky and secure looking lock. I've had bikes stolen in the past (didn't even realise until a few days after) but I think this will help to prevent any more going missing.Two modes on the lock, armed and not armed. When armed, the alarm will sound after a few seconds if the lock is moved even a little so if you are parking it in public where it might be nudged, better to not arm the alarm.

It's a good, chunky, sturdy lock - and will certainly deter opportunistic thieves.I've found the alarm can be a bit sensitive though - wind has set it off a couple of times, and it does have a habit of going off in the short time between me picking it up and turning the key to unlock it. Fine out in the open, but painful in a small enclosed area!Also - why is it so short! Give it an extra foot or so.

While it is a sturdy lock and cable the alarm part of the unit is not sufficiently resistant to the elements making the alarm feature useless. Better off looking for a weather proof alarm system or buying a traditional lock and cable/chain.

This security device is excellent for the price. It came with batteries supplied and with spare batteries. The only problem is that the instructions do not give enough information on how to replace the batteries. Once the battery chamber was opened, accessing the battery holding cassette required use of a screwdriver to lever it out of the chamber.

Very impressed with the lock. At first thought it wasn't sensitive enough, then realised it's very clever it's more sensitive the more it's tampered with to give you enough time to unlock it without an ear piercing sound and if it's accidentally nudged. After receiving this clever little device I ordered another one immediately

It's very strong but a mite heavy for a bicycle. the alarm is very sensitive and very loud. Should scare 'em off.

I you want to use this outdoors do not waste your money.We used to secure and alarm bikes to a hired motorhome but the rain/damp entered the casing and rendered it unusable as an alarm
