    Big, heavy, solid. And my bike has not been stolen yet...

    This is my second one of these as my first was second hand, and in my care had endured 5 years of almost daily locking and unlocking bad weather and just general lack of care. eventually the lock mechanism gave up the ghost one day and i was stuck at work one day for half an hour trying to get the damn thing unlocked. So i bought a second to replace it, and i am very happy with it. Its pricey for a u lock but you get what you pay for and it is very good quality. The only disappointment is the frame bracket they give you to fit to the bike. its a pain in the arse to put on and does not do a good job of holding the lock in my opinion, so i have replaced it with an alternative.

    Flexframe let's it down

    A well made lock that feels as sturdy as it looks. The one letdown with this make is the flexframe bracket which is fiddly to fit and then doesn't provide the sturdiest of attachments for the lock. Needs constant tightening or the lock slips around and gets in the way.

    Solid, dependable lock

    Bought my first of these a years ago and (together with a cable) has kept my bike secure for a year, so I just bought a second one. Any issues with key sticking - remember to occasionally lubricate, and use the cover provided to keep rain out when in use.

    A good lock

    Solid but slightly smaller shackle than equivalent Abusi. Escutcheon fell off after time on a previous lock.However Holding up well otherwise. Not really that heavy for protection offered. A great visual deterrent.Good keys. Okay mount.

    Great when it works

    We purchased this lock and it jammed shut after the first two weeks of use...however Tredz were brilliant with customer service and replaced it no worries... it is a good lock though as I had previously purchased one which is working fine... just a glitch with this one... as everyone says it is heavy but then it has a job to do!!

    You get what you pay for

    Really good quality sturdy lock as you would expect from Kryptonite. The key can occasionally be difficult to turn but otherwise works well.

    Very good but heavy lock

    One of the strongest D locks good quality unlikely to jam unlike some cheaper competitors offerings. But its heavy approx 2 kg therefore one to use in the city not for day rides.

    Very sturdy lock

    Before getting this lock Id never left my road bike out on the street. This lock seems substantial enough to deter most attempts at theft. Not as heavy as I thought it would be after reading other reviews.

    Heavy

    Secure lock but very heavy. Bracket could be more substantial.
