Query: Totally useless and defective design

This lock is defective through design and as other reviews state the bracket is indeed in the wrong position which just proves what a poor company Kryptonite is if they do not even proof test their own products. My lock broke after only 2 days after the key snapped in the barrel with only a mild wiggle. The locking mechanism itself struggled to open from day one. After my key snapped I was forced to borrow a cutter which tore the bar to shreds in 4 minutes.This lock is extremely easy to cut and it's in fact quicker to walk to a hardware store and buy a disc or cutter than actually use the key. IF you try use the key you will be there all day.Do not buy this product as it is defective and even dangerous by design.
