Replacing an outdated (yet reliable) micro-usb rear light. This worked great. Though I did put in some spacers for a better fit, I appreciate that the provided quality hardware was long enough to allow me to do this. This comes in the default position for Garmin, but is designed to be adjusted to Magne compatible. A definite plus. It is of sturdy construction, and designed to accept various mounting hole location scenarios. Review: Works great with Ortlieb E-Trunk bag and its bottle cage mount - Great little adapter. I have one of these attached to an Old Man Mountain Rack and to an Ortlieb E-Trunk bag. This purchase was for the E-Trunk bag to use with a Garmin Varia Radar (see photos). I undid the bolts for the quarter-turn mount, rotated it 90° and re-attached it to make it work for my E-Trunk bag (with the Varia Radar). With the generous spacing for the bolt-on mounts, I was able to thread the lanyard for the Varia case through just in case the quarter-turn mount gets bumped or comes loose. Installation, including unthreading the quarter-turn mount and reattaching, and then bolting into the E-Trunk bag took about 3 minutes. I'm super-happy to be able to know that when I click on my E-Trunk bag onto my e-bike that I'll also have my Varia Radar attached. The positioning of the mount on the E-Trunk bag works well, also, as the radar is about as far back as it can be and won't have any obstructions (versus having it mounted to the seat or seatpost on the bicycle). I'll get an alert when vehicles are approaching from behind, and they'll be able to clearly see the light flashing back at them. ## Features - 【DEDICATED TO SAFETY】 TUSITA is dedicated to rider safety.

It fits really well. The 2 screws included were a little too long. But I got some M5 screws 10mm that fit perfectly.
