Bully Locks 12MM Black Mamba Chain With Integrated Lock

Too heavy so I returned it.Worst part I had to pay for my own return label, $34 dollars!!!

Tough as GIANT nails! Heavy as hell! I love the twist away dust cover over the keyhole!

This the second one of these I have bought. Both have same problem.You get three keys. All have cheap rubber heads. When twist the key to lock or unlock the rubber head strips right off leaving the slim metal key part in the lock.You can not turn the slim metal key part or remove it from the lock without pliers. So I carry pliers in my saddle bag so can use the lock.Contacted thier customer service several times to order additional keys. Was willing to pay for them what ever the cost because I do like the chain. NEVER HEARD BACK FROM CUSTOMER SERVICE. Not even one reply.So you will have a useless lock unless you carry pliers. And if the rubber strips off the key whike you are somewhere out and about locked you are stuck until you find pliers to unlock it.I won't be buying a third one that's for sure. GL.

Heavy duty chain is nice, but the lock itself is hard to unlock at times and gets jammed. I always keep the keyhole cover in, but dirt still gets into the lock somehow causing it to be stiff and hard to turn the key

Heavy as heck, this lock isn't going anywhere. I get a work out just lifting it, but that's fine because I use it to lock up my bikes in my garage. I like how long it is. I can loop three bikes together easily. Lock is nicely designed with a sliding cover that protects the key hole from the elements.

The only thing bad you can say about this lock is it’s heavy weight. It costs less than half of what a Kryptonite Forgetabout it lock does ,but has more chain, a lighted third key, a very important lock cover ( keeps dirt,dust and water out of keyhole) and the very look of it wrapped around your bike is a deterrent . Again, it is heavy, but it does provide an awesome sense of security.

I purchased one of these at the dealership when I bought a new motorcycle. This was far and away the worst purchase I ever made in my life. I have to fight like hell just to get the key back out of the lock. I've already broke two of their cheap keys. I can't even put a dollar amount on the amount of money I feel this company owes me for all the aggravation. Even if they went into receivership and sold all their assets and gave it to me it would STILL NOT BE ENOUGH!

Big, heavy = just want I wanted. Would think it would be very difficult for someone to break. I would not recommend this for a commuter lock for a bicyclist. I got this to lock my two bicycles in the garage while my garage door is open. Figured a combined weight of 80#s stuck together would be very awkward for someone to steal...
