Pros: Product has a good,solid, feel to it. The design is well thought out, preventing access to wheel nuts. Gives the impression that it could survive quite a significant attack. Cons: Took me little while to figure out how to put it all together.
Once assembled it can be tricky to get the locking mechanism to locate and lock properly - I understand this is a common complaint with this item - the rest of the riders had a 20 minute head start on me on one occasion!
