Darlington GB
Easy to lock
Can easily rotate whilst in carrying bracket on frame. This could catch and injure your leg. Short strap avoids this.
When fully inserted into carrying bracket, it is fiddly getting out. Remedy: dont push it right in - it wont pop out !

Norwich GB Daily commuter cyclist.
Fast shipment, good and sturdy lock for its price. Slightly fiddly key operation - not unusual for more secure D-locks - but otherwise very good product!
