I bought these mirrors and have them on my Roxor now. My review would be that overall I am satisfied with them and would likely buy them again if needed. What I like most is that they bolt right up to mounting holes that are already on the chassis and so they look like they are factory. The possible advantage the others have, that mount to the roll cage, is that the mirrors can be mounted higher up, more at eye-level. These are mounted quite low compared to eye level...lower than the side mirrors would be in a truck or car. Am pretty sure that is why the Jeep CJ5/7 mirrors are higher.
