You can read our review of the Stoplock Pro on the Honest John Kit website here - kit.honestjohn.co.uk/reviews/stoplock-pro-review/ - we have not tested the Pro Elite version of this product, but the Elite version has the advantage of a design that makes it compatible with a larger range of steering wheels and twin locking forks for additional security. At some retailers such as Halfords the price difference between the Pro and Pro Elite is minimal, so it would be an easy option to go for the top of the range version.
