Blackburn Sing Sing U-Lock Reviews:

Positive Reviews:

Awesome bike lock. Comes with a mount for your bike so you dont need to carry it in your bag. Three keys so you can loose a few and still be in the clear. Great lock, get it.

Negative Reviews:

The blackburn locks are good quality and make it more likely your precious bike will still be there when you get back, but they're not perfect. The bracket is flimsy and the lock's outside edges are raw metal, perfect for removing paint.
The theft replacement guarantee is the real killer though. It only applies if you live in certain states within the US and Canada. You have to register the lock within 15 days of purchase, providing a wide array of paperwork and also payment. That's right; the guarantee isn't included in the price of the lock and is instead an optional extra.
Since the lock registration form isn't enclosed with the lock and no mention of it is made on the packaging or website, odds are you'll have had it more than 15 days before you know you need to fill out the form, let along get hold of one and send it back.
