Could not be more pleased with this mounting option. After using the rubber mounting strap that comes with the light, I kind of see this as a must have for Stix lights. Installation is super easy, as it just screws into designated holes on your saddle. Once installed, it provides a super secure and snug fit for your light. There is no jostling or dislodging on bumpy rides. I use this is conjunction with the rack mount, and really like that I have visibility from two different heights. I also just really like having a secure mount without any rubber straps. It looks super clean and sleek. Quite a few folks at stops have complimented how clean it looks - Not an absolute necessity, but I'm super picky about appearance so it's a big plus.
