i wouldn't pay 20bucks for that. its a good walmart lock, but a bad bike lock. to be honest your better off buying the top of the line lock Fahgettaboudit for 65 bucks on ebay(or a newyork series). what cost more 65 dollar lock or a whole new bike? really you should use two 2locks or ulock with a chain, but even that is cheaper than any new bike and most bikes on craigs list. and think of the peice of mind you buy, just 45 dollars more such a better lock and it only weights ~2pounds more. not a big deal.
