Not hardened!
I bought this chain to secure a generator. I decided to test the chain to ensure my generator was secure. My bolt cutters cut through this chain very easily, i am extremely skeptical that this chain is actually hardened. I used a punch on one of the links and a piece of mild steel and the dimple left in both were very similar. All of that being said the lock is well built not sure if the shackle is actually hardened but it has some very good design features. One thing this lock and does is give a very strong appearance of security. Which is probably all that is needed to deter most thieves.

Great Product
Lock and chain are much bigger than they appear in the picture. I was extremely happy when I went to the store and saw how large this lock/chain was. I got for the sale price 29$. I think I'm going to order about 3 more for other items I keep on trailers and in the back of my truck! Great deal. No flaws with this product.

PROS: Big, Strong, Looks good, Sturdy, Heavy duty

BEST USES: Secure Bikesmotorycles, Secure Genorators

gets the job done
cant beat it for the $29 sale price, wouldnt pay full retail for it though. its 10mm links are square so thats the "resist cutting" part. the sleeve is a nylon like material so it wont scratch paint. the lock is bulky like i like it and has a sliding cover to keep water/dirt out. the keys are cut similar to xena keys which is nice. im sure if someone was smart and strong with a big chain cutter they could punch through, but i still use this in conjunction with my alarmed xena disc lock for added piece of mind. if i was paranoid id stick with an onguard rottweiler or beast chain as they are much thicker, but this gets the job done.

PROS: Lengthy Anti-scratch, Laser Cut Keys, Anti-scratch, Generous length

CONS: Links Could Be Thicker

BEST USES: Low Crimerate Areas, Use With Disc Lock

The lock itself isn't the best yet works every time.

Not Worth It! Bike Stolen
I bought this lock when I bought my R6 about a month and a half ago. April 15th, I had someone come break the lock with bolt cutters in tow places and take the bike. They left the lock so we decided to see how easy it was to get through. It was SUPER EASY! Not hardened at all. The chains links were not bad though which is why this review has any stars at all. You should see where they had tried to break the chain first and decided to go after the lock next. So now I'm out a $70 lock and a $3500 bike.

great chain until it got stolen
-really liked the bulkiness, the cover to protect paint and the lock system

-bike still got stolen but in the product's defense, the chain was laying on the ground (I didn't know about avoiding this flaw before) so I don't know if it's my bad use of the product or the thickness being too thin
