Review on Ultimate Security 12mm Cut-Proof Bike Chain Lock with 16mm U Lock - Heavy Duty Disc Lock for Bicycles & Motorcycles - 3 Keys Included (3-Feet, Black) by Jeff Kern

Nice welds on the chain. A quality medium/heavy duty case over the chain that looks and feels like a great deterrent and durable security feature for even a well equipped bike thief. Now admittedly I didn't read the lock specs on the websites, it's a bit smaller than I thought it would be. It's just that when you open the lock it looks like a lot of plastic and a few flimsy metal grommets around the original deadbolt lock. Also inside this part of the castle is very bright so I just didn't like it. So I like the chain a lot, I say 4.5 stars 🌟 for the chain and only 3 stars 🌟 for the lock because of all the plastic around the lock, even though it's good, very strong, almost military grade plastic.
