Nice! Didn't notice it in the first pic. It's nice that your lock has slanted slots, makes locating the braze-ons less critical. Mine have vertical slots which don't always match the seatstay spacing. Those locks even hold the key while unlocked. Have three!!
They've been effective so far here in Toronto. A friend of mine in Rochester NY still had his bike taken but the thief couldn't go far because you can't roll the bike. Caught up to him and only suffered a broken spoke.
Wish I had one on my tandem. Got stolen last week in a snow bank at -15C.
