Bought two of these to secure a new farm gate that I had installed in my garden as the "Traveller community" like to turn up in my neck of the woods from time to time and invite themselves onto your land for as long as it takes the local law enforcement to get them to move, by which time they have destroyed the garden and nicked anything that's not nailed down and an unsecured entrance to the land is exactly what they look out for.I'm not sure how easy it would be to cut the chain (it would have to be cut as the chain links are welded) but the padlock is really decent, the lock is un-pickable and the shoulders around the locking bar means you cant break the padlock with the two spanner technique (check out youtube)Hopefully it will keep very much unwanted visitors off my property
