I was having trouble getting secure wheel nuts off my car, the garage had used too higher a torque setting. Because of it's shape this spanner lets you apply an even pressure when undoing nuts so that the security nut adapter does not get wrenched sideways during use. For home users this considerably speeds up wheel removal, compared to using the car manufacturer spanner. Seems strong during first use but can't comment on longterm reliability as I have only had it for a few days."
"Firstly I AM in the motor trade. I bought this item to keep at home, as our household has three vehicles with three different size wheel nuts. Pros: The sockets are all the right size and work well. The 23mm socket is not permanently attached, allowing you to use other sized sockets. Cons: The non permanent socket is a very loose fit and flies off very easily"
