Title: Strong but Difficult to Lock
Review: The quality of the lock is very good and the weight of it and my past experience with this brand give me confidence in its ability to protect my property. Unfortunately using the key is a bit tricky and a hassle. At first I thought it was "operator error" on my part but over time, it seems there really is a pattern that needs to be followed to engage the lock once it has been opened. It shouldn't be this hard. It takes multiple attempts and I have to be very thoughtful about how I remove the key, position the lock and then engage the locking mechanism every time I use it. Not sure I would buy this version again if I knew this in advance.

Title: Great bike lock.
Review: I got this as we got two new electric bikes (love)...and occasionally want to stop for lunch or a bathroom break and needed a way to secure them. This is a great lock for that purpose. They make a more expensive version, but this is just what we need.

Title: Lock review
Review: Seems sturdy, hasn’t been tested yet. The packaging for shipping did damage my lock as well. The holder barely fit on my small bike frame because the lock slides into the attachment so it has to have room for the lock plus about 4” of clearance.

Title: Great light duty lock.
Review: Know what this lock is for. This is a light duty lock for quick stops or a supplement. I use the New York lock as my main lock. It secures my frame and back tire to the rack. I use this to lock my front tire to the rack or to my frame. Thiefs can get through any lock so my theory is to make my bike harder to steal than someone elses so mine gets left alone. The wire works great to secure my seat and rack.

Title: Local thieves hate me
Review: Local bike thieves now hate me since I bought this lock. It is pretty safe as long as they are not subscribed to "Lock Picking Lawyer".

Review: L'ho acquistato tempo fa e funziona bene.In effetti una delle critiche è l'apertura o chiusura con la chiave, sembra che a volte si incanti e anche a me è successo.Basta avere un po di pazienza e riprovare, senza sforzare inserendo la chiave fino in fondo.L'arco non è enorme, quindi spesso con le rastrelliere di nuova concezione, è difficile riuscire ad assicurare il telatio, ma questo ritenfo non sia un problema del lucchetto bensì delle rastrelliere. Ho ancora la bici, cerco di essere ottimista sperando sia dovuto all'onesta delle persone e non alla dissuasione del lucchetto, ma nel dubbio il Kryptonite mi segue sempre
