Good lock, works smoothly, pinwheel cover fragile
Strong lock, works smoothly, rubber cover over pin wheels fall off regularly and is bound to be lost

very good quality - and quite strong, easy to change settings and open is a little heavier than I though but that makes it look VERY strong

Seized and had to be cut off
Used this on an outdoor bike shed, in a sheltered location. Occasional use only. After just over a year, it locked shut - the wheels could not be moved individually, they were all locked together. I had to get the angle grinder out and cut it off. Brand recognition led me astray - waste of money.
