Every single U-lock I have had within the past year has somehow jammed up or rusted up on me and I wasn't able to use the key with them without a long-winded struggle. I've tried Masterlock and the Bell brand.
I am about to buy a $50 Kryptonite Series 4 Evolution lock. Is this a good brand? Will it jam up or rust on me? Am I going to regret paying that much for it after a couple of months?
Any and all help you have to offer is much appreciated! Thank you!
