Warning - this castle is no reliable!

I have my bike for 6 weeks properly secured with this lock on bike racks, street lights etc ... Now it was cracked but on a busy street - Ratz Fatz were the 1000-wheel (and 85-castle) away. Hindsight is always smarter known but if you look around on YouTube, or the poorer reviews read, it also becomes clear how this could happen. My recommendation is a good U-lock (Abus / Kryptonite / ..) - although certainly not as nice handy in use or in transport, but I hope it saves many Radfahreren the frustration I experience degree.
