🔒 Master Lock Chain Lock: Standard Combination Bike Lock, 4 ft. Long, Red - Model 8147D Review

comes with a warning that it can cause cancer (which of course wasn't stated on the item description page). So I don't even know anything about the durability of the item

I used to have a standard Master cable lock that worked fine and came with a key. After hearing about bike thefts in my area, I decided to "upgrade" the stock cable lock to this chain lock, naively believing it would be more secure than my 3/4-inch cable lock that was $10 at Target and probably cut out could be with kitchen scissors. About a week after I started using this chain lock (which I was very happy with prior to The Incident), upon returning to my apartment after a weekend out of town,
