Hab das Teil unter meinen Pro Stealth Carbon Sattel befestigt um meinen Garmin Varia so weit oben wie möglich zu befestigen. Das Teil ist super solide, nichts wackelt, klackert oder knarzt. Der Varia sitzt auch bombenfest und ich muss mir keine Sorgen machen, ihn unter der Fahrt zu verlieren. Lediglich der Preis ist etwas happig in meinen Augen. Ansonsten nur zu empfehlen.

Support pour selle de marque PRO.Ce Support convient parfaitement pour fixer sous la selle.J'ai fixé mon radar sans problème.A recommander pour les possesseurs de selle PRO.

Used it to mount my Varia radar. Works well.

UPDATED after contact from seller I have upgraded my review to 4 stars.The mount is 17mm between mounting screw locations and I misunderstood the description for the Pro thinking it was 60mm. It still works better than any other option I have at the present.I have it mounted on the back of my wife's XLAB Super Wing hydration rack with the use of single screw and a locknut and have ordered a 2nd adapter for her other bike.Otherwise, it does appear to be good quality and hope the seller will add a new option in the near future for this application.

Bought it just for the bolt on Garmin mount to attach a taillight to my road and gravel bikes. The slotted design allows movement of the taillight to adjust to seatbags and whatever you attach to your seat. It also completely secures the PRO rear fender. I am using it with the new WTB Graveleir seat.
