Technical Information

1
Security
Unlike what many people may think, tamper-proof locks do not exist. A bike lock is there to make stealing the bike more complicated, to delay the thief and therefore act as a deterrent. A good lock has an anti-picking lock mechanism and is made out of materials requiring the use of specific tools, therefore making theft more difficult.
2
Security rating.
The security rating helps you choose the lock which is most suited to your use. In order to do that, B'Twin has defined a test protocol with an independent laboratory, the CNPP, based on real-life theft techniques. This unique protocol allows each lock to be given a comparable rating which indicates how resistant it is against theft. This rating goes from 0 to 10.
3
Lock body
Links made of hardened steel (65 HRC), one of the highest strength levels available for bike locks. Guaranteed resistance to hacksaws and hammers. Covered in fabric to keep it from scratching the bike frame.
4
Lock
Reinforced lock mechanism. Hundreds of different keys to limit the risk of theft. Comes with 2 numbered keys.

Get it if you want to be worry free of your bike
Strong, is covered with a cloth to prevent scratch
Heavy-2.2kgs
chain very good, padlock not great
Nice heavy chain, but the padlock is very tempremental. Two or three times now its jammed so that you cant unlock it, the last time it took three of us over an hour to unlock the thing. Will take it back to swap for something else.
Response of the brand
Hello,
I'm sorry to read that the padlock is jamming. Have you tried squirting some grease/oil into the two holes for the U shaped shackle? Try to avoid WD40 which can be OK for un-jamming or to displace water but is also degreaser (which is is not always desirable).
If you leave your lock out in the rain then this is good practice. If however, you keep your lock indoors or under a shelter then there may well be an issue, in which case, please return it to us for an exchange.

Very strong looking lock, but NOT unbreakable
Used for More than 1 year
Had this lock for about 18 months, I used it to secure three bikes together in the shed.

Thought it would be strong enough to withstand attack, unfortunately not. Had two bikes stolen from shed, the third was left on the lawn, obviously not good enough for them, although it did cost £300!

The forensic officer said that bolt cutters had been used on the chain, not the lock. He was surprised and would be upgrading his own motorbike chain at it was smaller than this one.

I'll be looking for something more secure, when bikes are replaced.
Spare Keys
Used for More than 1 year
Where can I get spare keys from, I have the key number?
Could you please put this information on your web site
Strong and Heavy
Do not know where to get spare keys
Response of the brand
Unfortunately, we don't offer a key replacement service on our bike locks.  If you lose you keys, you will need to purchase a new lock.
If you contact me directly, I can help find a solution for you.

Seems a decent enough lock, but it doesn't have a Sold Secure Rating, so you can't really use it as your main bike lock, only as a backup/secondary lock.
Cheap
No Sold Secure Rating
Response of the brand
Hello,
This is indeed a very solid lock but it has not been sent off for testing with "sold secure".  It depends which insurance  company you use as not all require a sold secure rated lock (bronze, sliver,gold).
We do stock various rated locks from ABUS which may fulfill your requirements:

Silver: http://www.decathlon.co.uk/granit-plus-bike-d-lock-id_8316303.html or http://www.decathlon.co.uk/ionus-8900-chain-bike-lock-id_8203081.html
