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

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

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
