One review on there:
"I found that it didn't fit my clamp, as my standard allen bolt clamp meant it was upside down - and unlocked. A new clamp meant that this security system has cost almost £20 - over 6 times as much as my makeshift solution - which works just as well.
Great idea, but would I buy one again? Only if my bike had come standard with a quick release skewer that this could replace."
