I decided to purchase this lock after doing some research into what I was about to buy. I found other sources recommending ABUS locks (I believe the are part of the Assa Abloy group?) as a company that build secure locks that have a mix of anti bump and other security pins in the locks core.
The lock itself is of good construction, smooth operation and is designed for external use.
I purchased this from Safe.co.uk as it was at a good price and has lots of detail on the product on their website. After ordering I received it quickly.
I would recommend both the lock and safe.co.uk to others!
