Review on UBULLOX 3FT/4FT Bike Chain Lock - 5-Digit Combination Anti-Theft Bicycle Lock, Resettable Bike Lock Chain for Bicycles, Motorcycles, and More by Mike Meyers

The lock works well and is very easy to use. I like nice big tumblers that make dialing easier instead of some locks with small tumblers. And it works flawlessly. good length My only complaint is that it makes a rattling noise. So when you're going over a bump or on a bumpy road, it's a little annoying. I almost sent it back because of this. But then I started putting it in panniers that I attached to the rack so now I don't hear it while riding. Good value for money.
