I've always used a small bag under my seat, with a light below that, but I was worried the bag and/or rear tire would get in the way of the Varia I got recently.
With this kit, I'm able to keep my bag, and the radar/light gets mounted at the back of my set, behind my bag. I've had no issues with visibility or not picking up traffic behind me because it puts the radar at a good height without anything to get in the way. And, I get to keep using my bag.
If you have a bag that goes to about the rear of your seat, you're probably good to go with this kit. If you have something that extends to the rear a bit more, I'm thinking of bike packing bags or something like that, then you're probably going to need to figure something else out.
The perfect mount for the Garmin Varia line, and particularly for the heavy 715 model. I can still use a LizardSkins saddle bag with this mount too. Solid & high quality parts. So good I have it on multiple bikes.
