Review on Secure Your Bike With Titanker Anti-Theft Chain Lock - Resettable Combination For Bikes, Motorcycles, Doors & More! by Dave Seawell

I bought the Titanker bike chain lock, size 8mm and 3 ft, with the 4-digit combo lock. The lock came the next day (with prime shipping) and it is LEGIT. definitely some good weight to it, should ward off any potential bike thieves :) see photos with my bike locked up - 3 feet gets you close enough to wherever your anchor-point is to the bike frame, without any extra slack. I live on the peninsula in Newport Beach, CA and tourists are beginning to flood in here, so I'm feeling a lot more confident leaving my bike locked up outside with this chain lock - thanks for the quick delivery, Titanker!
