Review on OnGuard Pitbull U Lock Black 9 06 Inch by Jose Guzman

Used it as the only lock on a crappy bike in the big city for a while with no problems. I upgraded my bike and now this is my extra lock. Good size for mounting on scaffolding/odd spaces. Although I see a lot of such clippings (RIP). For now, it's fine for making stealing my bike more inconvenient, although I wouldn't trust it alone on a $500 bike in a big city. Never had a problem with the locking mechanism. However, the bracket can rattle a bit and has bounced off curbs a few times.
