Excellent bike lock
Much more theft proof than my old cable bike lock which was easily defeated by a bolt cutter. Very pleased with my purchase.

Could be bigger
Not big enough for some of the racks around where I live but it's sturdy

Worth the money
Bought this for my step son. He uses it to lock up his e-bike. He hasn’t had any problems or issues thus far. He said the mechanics work well and it’s easy to use.

Not a keeper
POS. Get to my destination, key won't turn. Take it out and put back in a several times trying to get the insides to align, but no. Finally try to force it, thinking its small imperfection but key snaps off inside it and now its worthless. $50+ down the drown.
